Question

A gas can is filled at the rate of 320 cubic inches per minute. The cab is 10 inches long, 8 inches wide, and 12 inches high. How many minutes will it take to fill the can?

Answer 1

The can is 10 inches long, 8 inches wide, and 12 inches high.

As, Volume of cuboid = $l \times b \times h$

Volume of can = $10 \times 8 \times 12$ cubic inches.

So. Volume of can = 960 cubic inches.

Since, a gas can is filled at the rate of 320 cubic inches per minute.

Therefore, total minutes taken to fill the can = Volume of the can $\div$ Rate at which gas is filled

= $960 \div 320$

= 3 minutes.

Therefore, it will take 3 minutes to fill the can.

Answer 2

3 minutes
10*8*12=960 cubic inches
960/320inches per minute =3
