Using the formula v=bxh what is the volume of a rectangular prism with a length of 10 2/5 inches a width of 8 1/2 inch and a height of 6 1/4 inch. Your answer should be a mixed number in the simplest form.

First, we need to convert all the mixed numbers to improper fractions:

Length = 10 2/5 = 52/5
Width = 8 1/2 = 17/2
Height = 6 1/4 = 25/4

Now, substitute these values into the formula:
V = (52/5) x (17/2) x (25/4)
V = (52 x 17 x 25) / (5 x 2 x 4)
V = 22100 / 40
V = 552.5

Therefore, the volume of the rectangular prism is 552.5 cubic inches, which can be simplified to 552 1/2 cubic inches.
