Solution

Length of the tank = 10 m

Breadth of the tank = 7.5 m

Depth of the tank = 3.8 m

Area of four walls = 2[L+B] x H = 2(10 + 7.5) x 3.8

= 2 x 17.5 x 3.8 = 35 x 3.8 = 133 m2

Area of the floor = L x B = 10 x 7.5 = 75 m

Area of metal sheet required to make the tank =Area of four walls + Area of floor = 133 m2 + 75 m2 = 208 m2
