Question

The length of a cold storage is doubled its breadth and its height is 3cm the area of its 4 walls is 108cm^2. Find its volume.

Answer 1

Answer:

let b=x

then l=2x

h=3 cm

area of 4 walls = 2h (l+b)

                     108= 2×3 (2x+x)

                     108=6×3x

                      3x=108/6    

                      x=18/3

                      x=6cm

b=6cm

l=12cm

      Volume of cuboid=lbh

                                    =12×6×3

                                    =216cm³

Answer volume of cuboid is 216cm³
