A water tank has a square base of area 5 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, starting at t=0, at the rate of 2 + 4 t cubic meters per hour. Here t is the time in hours. What is the depth of water remaining in the tank after 3 hours

Step-by-step explanation:

= Surface area of base = 5 square meters

Volume of water in tank = 70 cubic meters

The rate at which the volume is reducing is

Integrating from to

Volume of water remaining in the tank is

Suface area of base depth = Volume

The depth of the water remaining in the tank is .
