Using the formula V = B × h, what is the volume of a rectangular prism with a width of 2 1/4 in., a length of 3 1/8 in., and a height of 1 1/ 2 in.?

First, we need to convert the mixed numbers to improper fractions for easier calculation.

Width (w) = 2 1/4 = 9/4
Length (l) = 3 1/8 = 25/8
Height (h) = 1 1/2 = 3/2

Now, we can plug these values into the formula V = B x h:

V = (9/4) x (25/8) x (3/2)
V = (225/32) x (3/2)
V = 675/64

Therefore, the volume of the rectangular prism is 675/64 cubic inches.
