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

Answer 1

`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)`
