Answer:

The surface area is
$198.75\ ft^2$

Explanation:

Step 1: Determine the area of the bottom

A = s^2

$A = (7.5\ ft)^2$

$A = 56.25\ ft^2$

Step 2: Determine the area of the triangles

A = (h * b)/(2)

$A = (9.5\ ft * (7.5\ ft)/(2))/(2)$

$A=(9.5\ ft*3.75\ ft)/(2)$

$A = 17.8125\ ft^2$

There are two of these right triangles on every side which means that we have 8 of these triangles so we multiply the area that we got by 8.

$A = 17.8125\ ft^2 * 8$

$A=142.5\ ft^2$

Step 3: Combine the area to get the surface area

$A_(total)=56.25\ ft^2+142.5\ ft^2$

$A_(total)=198.75\ ft^2$

Answer: The surface area is
$198.75\ ft^2$
