NEED HELP WITH A MATH QUESTION WITH FINDING A SURFACE AREA OF A SQAURE PYRAMID

Answer 1

ANSWER

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

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!

$S.A = 4 \times \frac{1}{2} bh + {l}^{2}$

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

We substitute the values to get:

$S.A = 4 \times \frac{1}{2} \times 5 \times 10 + {5}^{2}$

This simplifies to;

$S.A = 100 + 25$

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