Final answer:
The volume of the bed of the dump truck is found using the formula for the volume of a rectangular prism and is calculated to be 720 cubic feet.
Step-by-step explanation:
To calculate the volume of the dump truck's bed, we can use the formula for the volume of a rectangular prism, which is Volume = length × width × height. Raphael's dump truck has a bed with the dimensions of 15 feet in length, 8 feet in width, and 6 feet in height.
Using these dimensions, we find the volume of the dump truck's bed as follows:
- Volume = 15 ft × 8 ft × 6 ft
- Volume = 120 ft × 6 ft
- Volume = 720 cubic feet
Therefore, the volume of the bed of Raphael's standard-sized dump truck is 720 cubic feet.
