What is the volume of a rectangular prism with a length of 4 2/3 ft., a height of 3 1/3 ft., and a width of 2½ ft.?

To find the volume of a rectangular prism, you simply multiply the length, width, and height together.

Let's convert the mixed numbers to improper fractions for easier calculation:

Length: 4 2/3 ft. = 14/3 ft.
Height: 3 1/3 ft. = 10/3 ft.
Width: 2 1/2 ft. = 5/2 ft.

Now we multiply:
Volume = (14/3) ft. * (10/3) ft. * (5/2) ft.
Volume = (140/9) * (5/2)
Volume = 700/18
Volume = 38.89 ft^3

Therefore, the volume of the rectangular prism is approximately 38.89 cubic feet.
