1) What is the surface area?<br> 1 ft<br> 8 ft<br> 4 ft
WITCHER [35]

Answer:

88 ft^2

Step-by-step explanation:

For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions

<em>1 ft by 8 ft, </em>

two opposite faces with dimensions

<em>1 ft by 4 ft, </em>

and two opposite faces with dimensions

<em>4 ft by 8 ft.</em>

We find their area and add them.

SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft

SA = 16 ft^2 + 8 ft^2 + 64 ft^2

SA = 88 ft^2
