Apply the formula V=B×h. What is the volume of a rectangular prism with a height of 3 2/5 ft., a length of 6 1/8 ft., and a width of 7 1/4 ft.?
First, convert all the mixed numbers to improper fractions:
Height: 3 2/5 ft = 17/5 ft
Length: 6 1/8 ft = 49/8 ft
Width: 7 1/4 ft = 29/4 ft
Now, plug the values into the formula V=B×h:
V = (49/8) * (29/4) * (17/5)
V = 49 * 29 * 17 / (8 * 4 * 5)
V = 23839 / 160
V = 149 ft^3
Therefore, the volume of the rectangular prism is 149 cubic feet.
