ANSWER

$S.A = 125 {in}^(2)$

Step-by-step explanation

The total surface area of a square pyramid is the area of the 4 triangular faces plus the area of the square base.

This is given by the formula!

$S.A = 4 * (1)/(2) bh + {l}^(2)$

From the diagram, the base is 5 inches and the height is 10 inches.

We substitute the values to get:

$S.A = 4 * (1)/(2) * 5 * 10 + {5}^(2)$

This simplifies to;

S.A = 100 + 25

$S.A = 125 {in}^(2)$
