7.3CH Volume of a Cylinder
Go over # 24 on page 261
A rectangular tank, 40 m long by 30 m wide, is filled with 960 m 3 of water.
a) Determine the depth of water.
1. If the water drains out at a rate of 60 m3/h, how much water is left after 2.5 h?
What is the new depth of water
1. Later, the depth of the water is 0.2 m. For how long has the tank been draining?
1 ml = 1 cm3
1000 ml = 1 liter = 1000 cm3
