Question

Sonia made a cuboid of side 5 cm 6 cm 4 cm . How many such cuboids will she need to make a Cube

Answer 1

We know

6×5×4=120

as 120 is not a perfect cube

and by prime factorisation 120=2×2×2×3×5.

so to make it a perfect cube we need to multiply it by 5×5×3×3=225

and 225×120=27000..

And so she will require 225 cuboids to form a cube..
