Each face of a cube has an area of 400 cm2. what is the volume of the cube?
1 answer:
A cube is a square shape, so both sides ( length and width) of a face would be the same.
Find the length of the side by finding the square root of the area of the face:
Length = √400 = 20 cm.
Volume is Length x Width X height.
Volume = 20 x 20 x 20 = 8,000 cm^3
