| **The volume of a rectangular parallelepiped-shaped tank is 810 dm3, the height is 9 dm, find the area of the base of the tank.**

The volume of a rectangular parallelepiped is equal to the product of the height, length and width of this parallelepiped. The base of this parallelepiped is a rectangle whose area is equal to the product of the length by the width of the parallelepiped. Thus, to find the area of the base, you need to divide the volume of the parallelepiped by its height:

810/9 = 90 (dm2).

Answer: 90 dm2.
