Question

9. A cuboid having the dimensions as 12 m x 8 m x 18 m is melted to form a cube. Find the length of
each side of the cube.

​

Answer 1

Answer:

Dmensions of a metalic cuboid are18m 12m 8m

It's volume = 18 x 12 x 8 m cube

= 2 x 3 x 3 x 2 x 2 x 3 x 2 x 2 x 2 m cube

=2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 = (2 x 2 x 3)3 cube

It is a perfect cube ,hence we can make a cube using it's molten metal.

So, it is not necessary to add a molten metal in it .
