Find the surface area

Semmy [17]

Answer:

The surface area is $198.75\ ft^2$

Step-by-step 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

$A = \frac{h * b}{2}$

$A = \frac{9.5\ ft * \frac{7.5\ ft}{2}}{2}$

$A=\frac{9.5\ ft*3.75\ ft}{2}$

$A = 17.8125\ ft^2$

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 $198.75\ ft^2$
