3. Dice are cubes where the numbers on the opposite faces must total 7. Which of the following are dice?

Solution:

Figure (i), is a dice. Since the sum of numbers on opposite faces is 7 (3 + 4 = 7 and 6 + 1 = 7).

4. Draw nets for each of the following polyhedrons:

Solution:

(i) The net pattern for cube is

(ii) The pattern for triangular prism is

(iii) The net pattern for hexagonal prism is

(iv) The net pattern for pentagonal pyramid is

5. Match the following figures:

Solution:

(a)-(iv) Because multiplication of numbers on adjacent faces are equal, where 6Ã—4 = 24 and 4Ã—4 = 16

(b)-(i) Because multiplication of numbers on adjacent faces are equal, where 3Ã—3 = 9 and 8Ã—3 = 24

(c)-(ii) Because multiplication of numbers on adjacent faces are equal, where 6Ã—4 = 24 and 6Ã—3 = 18

(d)-(iii) Because multiplication of numbers on adjacent faces are equal, where 3Ã—3 = 9 and 3Ã—9 = 27
