The area of the base of a rectangular tank is 6500 sq. cm and the volume of water contained in it is 2.6 cubic meters. The depth of water is?

3.5 m
4 m
5 m
8 m

Correct Answer: 4 m

Explanation:

Let depth = D cm.
Then, D x 6500 = 2.6 x 100 x 100 x 100
∴ D = (2.6 x 100 x 100 x 100) / 6500 cm
= 400 cm = 4 cm
