Question

Find the surface area of the square pyramid shown below. (Measurements in picture)

Answer 1

Given:

Side length of base = 8

Slant height = 6

To find:

The surface area of the square pyramid.

Solution:

Surface area:

$SA=A+\frac{1}{2} p s$

where A is the area of base

p is the perimeter of base

s is the slant height

Area of base (A) = 8 × 8

                           = 64

Perimeter of base(P) = 4 × 8

                                  = 32

Substitute these in the formula:

$SA=64+\frac{1}{2} \times 32 \times 6$

$SA=64+96$

$SA=160$

The surface area of the square pyramid is 160 unit².
