Question

A cuboid has total surface area of $372c{m}^2$ and its lateral surface area is $180c{m}^2,$ find the area of its base.

Answer 1

$\text{Total surface area of a cuboid}=372c{m}^2$

$\text{and lateral surface area}=180c{m}^2$

$\therefore \text{Area of base and roof}=372-180=192c{m}^2$

$\text{and area of base}=\frac{192}{2}=96c{m}^2$
