The dimensions of the can are 10 inches long, 8 inches wide, and 12 inches high. The volume of the cuboid can is calculated as follows: Volume of the can = 960 cubic inches. Given that the gas can is being filled at a rate of 320 cubic inches per minute, we can determine the total time needed to fill the can by dividing its volume by the filling rate: Total minutes to fill the can = Volume of the can divided by the Rate at which gas is filled = 960/320 = 3 minutes. Therefore, it will take 3 minutes to completely fill the can.
