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
