To find the volume of the rectangular prism, we need to plug in the values for the width (B), length (l), and height (h) into the formula V = B x h.
Width (B) = 3 1/4 in. = 13/4 in.
Length (l) = 5 1/8 in. = 41/8 in.
Height (h) = 7 3/8 in. = 59/8 in.
Now, plug in the values into the formula:
V = (13/4) x (41/8) x (59/8)
V = 13 x 41 x 59 / (4 x 8 x 8)
V = 33467 / 256
V = 130 67/256 cubic inches
Therefore, the volume of the rectangular prism is 130 67/256 cubic inches.
