You would take 3 x 4 which equals 12. And then you would take 12 x8 which would equal 96
Volume of the first aquarium = (12" x 13" x 14") = 2,184 inches³
Volume of the second aquarium = (32" x 34" x 35") = 38,080 inches³
The second aquarium has (38,080 / 2,184) = 17.44 times as much
volume as the first aquarium has.
So it'll take the hose 17.44 times as long to fill the second one
= (17.44) x (2 minutes) = 34.9 minutes.
Adding 220 + 360 = 580 total students.
5% of 580
(5/100)*580 = 29
