The can is 10 inches long, 8 inches wide, and 12 inches high.
As, Volume of cuboid = [tex] l \times b \times h [/tex]
Volume of can = [tex] 10 \times 8 \times 12 [/tex] 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 [tex] \div [/tex] Rate at which gas is filled
= [tex] 960 \div 320 [/tex]
= 3 minutes.
Therefore, it will take 3 minutes to fill the can.
