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.

###### Advertisements

#### Solution

Volume of a rectangular solid = 1.92 m^{3}

Breadth of a rectangular solid = 1.20 m

Height of a rectangular solid = 80 cm = 0.8 m

We know

Length x Breadth x Height = Volume of a rectangular solid (cubical)

Length x 1.20 x 0.8 = 1.92

Length x 0.96 = 1.92

⇒ Length = `1.92/0.96`

⇒ Length = `192/96`

⇒ Length = 2 m
