Question

Find the surface area of a square pyramid with base length of 16 cm and a slant height of 20 cm

Answer 1

Answer:

The surface area of the square pyramid is 1,040 $cm^{2}$

Step-by-step explanation:

To find the surface area of the square pyramid, we make use of the mathematical formula.  

Mathematically, the formula for calculating the surface area A  of a square pyramid is :

SA = $s^{2} + 2sl$ where s is the slant height and l is the base length

From the question, we can see that the slant height is 20cm and the base length is 16cm. We plug these into the equation above;

SA = $20^{2} + 2 * 16 * 20$ = 400 + 640 = 1,040 $cm^{2}$
