Question

Find the surface area of the square pyramid

Answer 1

The surface area of the square pyramid is 40 units².

Explanation:

As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:

`A=2bs+b^2`

From the figure, it is clear that

• length of its base = 'b' = 4

• slant height = 's' = 3

substituting the values in the formula

`A=2bs+b^2`

`A=2\left(4\right)\left(3\right)+\left(4\right)^2`

`=2\left(4\right)\left(3\right)+16`

`=40`

Therefore, the surface area of the square pyramid is 40 units².
