Do now: These cuboids are all made from 1 cm cubes. Can you find their volumes and surface areas?
State the units in your answers. 1 2 3 4 5 6

2. How well did you do? Did you show calculations ?1 2 3
V = 1 x 2 x 4 = 8cm3
V = 3 x 3 x 3 = 27cm3
V = 2 x 2 x 4 = 16cm3 4 5 6
V = 3 x 3 x 5 = 45cm3
V = 4 x 4 x 2 = 32cm3
V = 2 x 4 x 4 = 32cm3

3. How well did you do? Did you show calculations ?1 2 3
SA = 2 x x x 2
= 28cm2
SA = 2 x x x 8
= 40cm2
SA = 2 x x x 9
= 54cm2 4 5 6
SA = 2 x x x 15
= 78cm2
SA = 2 x x x 8
= 64cm2
SA = 2 x x x 16
= 64cm2
