Find the weight of the right rectangular prism with length 13 ft, width 6 ft, and height 2.5 ft if the contents weigh 0.02 pounds per cubic inch.
I think that the answer is 3.9 by multiplying 6 x 13 x 2.5 x 0.02. Is this right?

if i can remember correctly the volume of a triangular prism the formula is:
volume = (1)/(2) * length * width * height
so i think you are okay
