Find a multiple of 50 which is a perfect cube.

50 x 20 = 1000

which is the cube of 10

Answer 2

Answer:

10

Step-by-step explanation:

Parikshit has a cuboid of dimensions 5×2×5.

And a cube should have equal dimensions.

To find minimum number of cuboids required to make a cube we need the L.C.M of the 3 dimensions

The first side: 5=5×1

The second side: 2=2×1

The third side: 5=5×1

Parikshit requires ten cuboids to form a cube of side 5×2=10 as 10 is the L.C.M of the numbers 5,2,5
