Final answer:
The volume of the U-Store It storage unit is calculated using the formula V = length × width × height, yielding 160 cubic feet.
Step-by-step explanation:
To find the volume of the U-Store It storage unit, which is in the shape of a rectangular prism, we use the formula for volume: V = length × width × height. Given the dimensions of the storage unit are 4 feet long, 5 feet in depth, and 8 feet tall, we calculate the volume as follows:
- Volume (V) = 4 feet (length) × 5 feet (depth) × 8 feet (height)
- V = 20 feet² × 8 feet
- V = 160 cubic feet
Therefore, the volume of the storage unit is 160 cubic feet, which corresponds to option (a) 160 cubic feet.
