1. The formula for calculating the surface area of a cube is:

SA = length × width × number of sides (6)

Therefore, the surface area of a cube that is 1 cm on a side is 1 cm × 1 cm × 6 sides = 6 cm2

2. The formula for calculating the volume of a cube is:

V = length × width × height

Therefore, the volume of a cube that is 1 cm on each side is 1 cm × 1 cm × 1 cm = 1 cm3

3. The surface area to volume ratio is:

SA ÷ V

For a cube that is 1 cm on a side, SA/V ratio is 6 ÷ 1 = 6.

Calculate the SA/V ratio for a cube that is 3 cm on each side.
