Final answer:
The height of the rectangular prism is 1.875 feet.
Step-by-step explanation:
To find the height of the rectangular prism, we can use the formula for volume: V = Bh, where B is the area of the base and h is the height.
In this case, the base is a square with sides of 8 feet, so the area is 8 * 8 = 64 square feet.
We know that the volume is 120 cubic feet, so we can substitute these values into the formula: 120 = 64h.
To solve for h, divide both sides of the equation by 64: h = 120 / 64 = 1.875 feet.
