Solution

Volume of a rectangular solid = 1.92 m3
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
