Question

The question is below?

The lateral surface area of a square based pyramid having equal edges is `144sqrt3 cm^2`. Find the area of the base.

Answer 1

Let the length of each edge be `a` cm.

Each lateral surface being a equilateral triangle the total area of lateral surface will be

`4*sqrt3/4*a^2=144sqrt3`

So `a^2=144cm^2`

This will be the area of square base.
