Step-by-step explanation:
Cube is a special form of cuboid in which length, breadth and height are equal i.e., all the dimensions of a cube are equal in measure. Therefore, 20 cuboids each of sides 5 cm, 2 cm, 5 cm will be needed to form a cube.

Step-by-step explanation:
Given numbers = 5\times2\times5
Factors of 5 and 2 both are not in a group of three.
Therefore, the number must be multiplied by = 2\times5\times2= 20 to make it a perfect cube.
Hence he needs 20 cuboids.
