Alternatively:
If the cubes edges are 5cm long, then you can find:
a) its total surface area (of the 6 square faces) = 5cmx5cmx6 = 150 square centimetres
b) its volume by multiplying length by breadth by height = 5cm x 5cm x 5cm =125cc (cubic centimetres
c) the total length of all of its edges, of which there are 12 measuring 5cm each
= 12 x 5cm = 60cm

Length X Width X Height Or if it's a perfect cube, just find one side and cube it.
The formula for volume is side cubed, and the formula for a square's area is side squared, so you find the cube root of the volume and square your answer to find area.
You find the surface area of a cube by using the formula 6e2. In this case, e=edge.
Four thirds of pi x the cube of the radius
