Question

The length, breadth and thickness of metallic cuboid are 78 cm 14 cm and 7 on respectively
melted and made into a cube. What is the edge of the cube so formed?​

Answer 1

volume of cuboid 7644cm³

so edge of cube should be (7644)¹/³= 19.69cm

Answer 2

$\huge{ \red{ \boxed{ \mathcal{ \bf{answer}}}}}$

length of cuboid= 78 cm..

breadth of cuboid= 14 cm.

height of cuboid= 7 cm

volume of cuboid= length x breadth x height

= 78×14×7 cm^3

= 7644 cm^3

volume of cube= volume of cuboid

volume of cuboid= 7644 cm^3

side^3 = 7644 cm^3

side =

$\sqrt[3]{7644}$

side = 19.7cm approx
