Question

Find the edge of a cube whose volume equals that of a cuboid whose dimensions are 63cm,56cm and 21cm

Answer 1

volume of the cuboid =lxbxh
=63x56x21=74088sqcm
volume of a cube= l^3
so l= (74088)^1/3
solving that would give you the answer.

Answer 2

here's ur answer!!!

volume of cube=volume of cuboid

volume of cuboid=l×b×h

=63×56×21

=74088cm³

volume of cube=74088cm³

s×s×s=7088cm³

side³=74088cm³

side= ³√74088

side=2×2×2×3×3×3×7×7×7

side=2×3×7

side=42cm

hence, final answer- the edge of the cube is 42cm.

hope this helps....
