A metal worker wants to figure out the cost of making a rectangular iron bar. He knows that the required dimensions of the bar are 8.0 cm (width), 0.40 cm (height), and 310 cm (length). If this kind of iron costs $0.015 per cm3, what is the cost of making the bar (to the nearest dollar)?

The cost of making the bar is $14.88 or rounded up to the nearest dollar $15.00

Given:
width = 8 cm
length = 310 cm
height = 0.40 cm
cost = $0.015 per cm³

Volume of a rectangular prism is solved by multiplying its length, its width, and its height.

V = l * w * h
   = 310 cm * 8 cm * 0.40 cm
V = 992 cm³

Total cost = Volume * cost per cm³
                = 992 cm³ * $0.015/cm³
Total cost = $14.88
