Step-by-step explanation:

I will answer this question with the attached square pyramid

From the attached pyramid, we have:

$Base\ Length = 20m$

So, the base area is:

Area = Length * Length

A_1= 20m*20m

A_1= 400m^2

The dimension of each of the 4 triangles is:

Height = 16.4m

Base = 20m

So, the area of 4 triangles is:

Area = 4 * 0.5 * Base * Height

A_2 = 4 * 0.5 * 20m * 16.4m

A_2 = 656m^2

So, the surface area is:

Area = A_1 + A_2

Area = 400m^2 + 656m^2

Area = 1056m^2

A square pyramid has 1 square base and 4 triangular faces. Find its surface area. A. The area of the
