The coal mine you manage has coal cars that are 3 feet wide by 4 fet long ad 1.5 feet deep. If a ton of coal equals 25 cubic feet, how many cars must be filled to complete an order for 15 tons of coal?

How do you compute the volume of one coal car (assuming that in cross section they are rectangles)?

How do you determine how many cubic feet are needed to hold 15 tons if 1 ton requires 25 cubic feet?

Volume Word Problem

The coal mine you manage has coal cars that are 3 feet wide by 4 fet long ad 1.5 feet deep. If a ton of coal equals 25 cubic feet, how many cars must be filled to complete an order for 15 tons of coal?

Volume of one car = (3)(4)(1.5) = 18 cubic feet

How many cubic feet in 15 tons given that
1 ton = 25 cubic feet?

1 ton/15 tons = 25/x

Let x = the amount of cubic feet in 15 tons

Can you take it from here?
