$SA = 920 inches^{2}$

Step-by-step explanation:

Given Data:

Slant height of square pyramid = l = 13 inches

Base edge of square pyramid = s = 20 inches

To Find Out:

Surface area of square pyramid = SA = ?

Formula:

$SA = s^{2} + 2 * s * l$

Solution:

$SA = s^{2} + 2 * s * l$

$SA = 20^{2} + 2 * 20 * 13$

SA = 400 + 520

$SA = 920 inches^{2}$
