You are designing an aquarium that is to have a tank holding 225,000 gallons of water. The tank will be 100 feet long and 20 feet wide. Note, 7.5 gallons = 1 cubic foot of water. How high will the tank need to be?

Respuesta :

225000 gallons = 30000 cubic foot

30000=100*20*x

x=15

The tank needs to be 15 feet high
