Question

The volume of a cuboid is $3456c{m}^3$ . If its length =24 cm and breadth =18 cm; find its height.
The breadth and height of a rectangular solid are 1.20 m and 80 cm respectively. If the volume of the cuboid is $1.92 m^{3}$; find its length.

Answer 1

Volume of a rectangular solid =$34.56c{m}^3$

Breadth of a rectangular solid $=18cm$

length of a rectangular solid $=24cm$

Here

$Length\times Breadth\times Height$ = Volume of a rectangular solid (cubical)

Substituting the values

$24\times 18\times height=3456$

By further calculation

$Length\times 432=3456$

$=\frac{3456}{432}$

So we get

height $=8cm$
