Answer:
length = 6 in
Explanation:
The general formula for the volume of a prism:
V = Bh, where B = the area of the base and h = height of the prism
Since the figure is a rectangular prism, the area of a rectangle is:
A = l x w, where l=length and w=width
Since you know the width, height and volume, you can plug these values in to solve for 'l':
V = l x w x h
60 = l(2.5)(4) or 60 = 10l
divide by 10: 60/10 = 10l/10
solve for 'l': l = 6 in
