Question

Find the capacity of a rectangular cisterm in liters whose dimensions are $11.2m\times 6m\times 5.8m$. Find the area of the iron sheet required to make the cistern.

Answer 1

The dimensions of rectangular cisterm is $11.2\times 6\times 5.8$

Volume is given by $lbh=11.2\times 6\times 5.8=389.76$

Lateral surface of Cuboid is given by $2h(l+b)=2\left(5.8\right)(11.2+6)=11.6\left(17.2\right)=199.52c{m}^2$

The base area is given by $l\times b=11.2\times 6=67.2$

The total area of iron sheet required is $199.52+67.2=266.72{cm}^2$
