Question 1

A cube has faces painted with colours: Red on top, Blue on bottom, Green on front, Yellow on back, White on left, and Black on right. When the cube is rotated such that Green face comes to the top, which colour will be on the bottom?

Accepted Answer

This question tests the understanding of opposite faces on a cube and how they remain opposite after rotation.

Question 2

A cube has faces numbered 1 to 6. Face 1 is opposite to face 6, and face 2 is opposite to face 5. When face 3 is on top, which face is at the bottom?

Accepted Answer

This question tests understanding of opposite faces on a cube using given constraints.

Question 3

A cube has six faces. Four faces are painted red, and two opposite faces are painted blue. If the cube is placed with one blue face on top, how many red faces are visible when looking at the cube from the front?

Accepted Answer

This tests the ability to count visible faces and understand the spatial arrangement of painted faces on a cube.

Question 4

A cube has its six faces painted with six different colors: Red, Blue, Green, Yellow, White, and Black. When the cube is unfolded, the net shows Red opposite to Blue, Green opposite to Yellow, and White opposite to Black. If you are looking at the Red face directly, and Green is on your right side, which color is on your left side?

Accepted Answer

Step 1: Identify the opposite pairs from the given information:
- Red is opposite to Blue
- Green is opposite to Yellow
- White is opposite to Black

Step 2: When looking at the Red face directly, Blue is behind (opposite side).

Step 3: Green is on the right side. Since Green's opposite is Yellow, Yellow must be on the left side.

Step 4: Verify: Looking at Red (front), Blue (back), Green (right), Yellow (left). The remaining colors White and Black must be on top and bottom respectively, which satisfies all opposite pair conditions.

Therefore, the color on the left side is Yellow.

Question 5

A die shows faces with dots: 1, 2, 3, 4, 5, and 6. It is known that opposite faces always sum to 7. If the die is placed with 2 on top and 3 facing you, what is on the bottom?

Accepted Answer

This question tests the standard die property where opposite faces sum to 7.

Question 6

A cube is unfolded into a net. The net shows a central square with four squares attached to its four sides, and one square attached to the top of one of those four squares. When folded, if the central square becomes the bottom face, which square becomes the top face?

Accepted Answer

This question tests spatial visualisation of cube nets and folding.

Question 7

A standard cube has faces numbered 1 to 6, where opposite faces always sum to 7. If face 1 is on top and face 2 is facing you, which face is on the bottom?

Accepted Answer

This question tests the fundamental rule of standard dice: opposite faces sum to 7. Students must apply this rule correctly to find the bottom face when top and front faces are given.

Question 8

A cube has six faces labeled A, B, C, D, E, and F. Face A is opposite to face B. Face C is opposite to face D. Which face is opposite to face E?

Accepted Answer

This question tests logical deduction using the constraint that a cube has exactly 6 faces forming 3 pairs of opposite faces. Given two pairs, the third pair must be determined by elimination.

Question 9

A cube has faces numbered 1 to 6. When face 1 is on top and face 2 is facing you, face 3 is on your right. Which face is at the bottom?

Accepted Answer

This question tests the ability to deduce opposite faces on a cube using spatial reasoning. Given three adjacent faces and their positions, the opposite face can be determined using the property that opposite faces of a standard cube are mutually exclusive.

Question 10

A cube is unfolded into a net. In the net, face X is adjacent to faces P, Q, R, and S. Which face is opposite to face X?

Accepted Answer

This tests the property that in a cube net, if a face is adjacent to four other faces, the remaining sixth face must be opposite to it. This is a direct consequence of cube geometry.

Question 11

A cube has six faces painted in different colours: Red, Blue, Green, Yellow, Orange, and White. Red is opposite to Blue. Green is opposite to Yellow. If Orange is on the front face, what colour is on the back face?

Accepted Answer

This question tests deduction of opposite faces using elimination.

Question 12

A cube has six faces painted with colours: Red, Blue, Green, Yellow, Orange, and Purple. Red is opposite to Blue. Green is opposite to Yellow. If Orange is on top, which colour is at the bottom?

Accepted Answer

This tests the ability to deduce opposite faces using given constraints. With three pairs of opposite faces defined, the remaining pair is determined by elimination.

Question 13

A dice shows face 1 on top and face 2 facing north. The dice is rolled forward (northward). After the roll, which face is now on top?

Accepted Answer

This tests the ability to track face positions after a single roll in a specified direction. Rolling forward moves the top face to the front and the back face to the top.

Question 14

A standard cube has faces numbered 1 to 6. When face 1 is on top and face 2 is facing you, which face is on the bottom?

Accepted Answer

This question tests the fundamental property of a standard die: opposite faces always sum to 7. If face 1 is on top, then face 6 must be on the bottom (1 + 6 = 7). The position of face 2 (facing you) is additional information that helps confirm the cube's orientation but does not change the top-bottom relationship.

Question 15

A die shows faces with dots: 1, 2, 3, 4, 5, and 6. When 2 dots are on top and 3 dots are facing front, which number is on the bottom?

Accepted Answer

This question tests knowledge of standard die properties where opposite faces sum to 7, combined with spatial positioning of three visible faces.

Question 16

A cube is painted red on all faces. It is then cut into 8 equal smaller cubes. How many smaller cubes have exactly 3 red faces?

Accepted Answer

This question tests spatial understanding of how a cube subdivides and which pieces retain painted surfaces. It requires counting corner pieces versus edge and face pieces.

Question 17

Two dice are placed such that they share one common vertex. Die A shows 5 on top and 3 facing front. Die B shows 2 on top and 4 facing front. If the two dice are now separated, what is the sum of the bottom faces of both dice?

Accepted Answer

This question combines the standard die property (opposite faces sum to 7) with the ability to track multiple dice independently, testing whether students can apply the rule to each die separately.

Question 18

A cube has faces numbered 1 to 6. When face 1 is on top and face 2 is facing you, which face is at the bottom?

Accepted Answer

This tests the fundamental property that opposite faces of a standard die sum to 7. If face 1 is on top, face 6 must be at the bottom. The question provides additional information (face 2 facing you) to make the scenario concrete, but the answer depends only on the opposite-faces rule.

Question 19

A dice has faces numbered 1 to 6. When 1 is on top and 2 is facing north, 3 is facing west. If the dice is rolled forward (northward), what number will be on top after the roll?

Accepted Answer

This tests the ability to track dice orientation through a specific rolling motion.

Question 20

A standard die shows 1, 2, 3, 4, 5, 6 on its faces such that opposite faces always sum to 7. If the die is placed with 2 on top and 3 facing you, which number is on the bottom?

Accepted Answer

This tests the fundamental property of standard dice where opposite faces sum to 7.
