Answer Key

- The circle and the square are examples of plane figures.
- 4
- Only (a) makes the cube.
- No, because one pair of opposite faces will have 1 and 4 on them whose total is not 7, and another pair of opposite faces will have 3 and 6 on them whose total is also not 7.
- 4100 cm2
- 27,000 blocks.
- a. Faces = 6, edges = 12, vertices = 8

b. Faces = 4, edges = 6, vertices = 4 - Matching of the figures is given below:
i) a) Rectangle ii) b) Cylinder iii) c) Triangle Iv) d) Trapezium
