Question

A cuboid has total surface area of 372 cm2 and its lateral surface area is 180 cm2, find the area of its base.

Short/Brief Note

Solution

We have,

Total surface area of the cuboid `(A) = 372 cm^2`

Lateral surface area of the cuboid `(A) = 180 cm^2`

Let,

a →Area of the base

We know that,

A = A' + 2a

`a = (A-A')/2`

  `=(372-180)/2`

  `=192/2`

   =96 cm2

Area of the base is  96 cm2
