Math CentralQuandaries & Queries


Question from mwenge, a parent:

What is the length ,width and height for the rectangular concrete tank that can have capacity of 50,000 liters of water?


One liter is 1000 cubic centimeters so 50000 liters is 50,000,000 cubic centimeters.

The volume of a rectangular tank is the length times the width times the height so if you have a tank with its length times its width times its height is 50,000,000 cubic centimeters then its volume is 50000 liters. So a tank that is 10,000 centimeters by 5,000 centimeters by 1 centimeter will work of one that is 5,000 centimeters by 1,000 by 10 centimeters will work as will 20,000 centimeters by 1,000 centimeters by 2.5 centimeter or many other possibilities.
