Question

A cuboid of sides 5cm 2cn 5cm how many such cuboids will he need to form a cube

Answer 1

We know that volume of a cuboid = 5 * 2 * 5

                                                          = 25 cm^3

LCM of 50 = 2 * 5 * 5

To make it a perfect cube multiply it with 2 * 2 * 5 = 20.

So, he needs 20 cuboids to form a cube.


Hope this helps!
