Then,
Hence, side of cube = 10cm
as we know that, surface area of cube
Hence, surface area of cube
Illustration: A solid cube of side 12 cm is cut into 8 cubes of equal volume. What will be the side of the new cube?
Solution: Let the length of the side of new cube be x cm. Then,
Volume of 8 cubes each of side x cm = Volume of solid cube of side 12 cm
As we know that volume of cube =
So, we have
Hence side of the new cube is 6 cm.
