D. 8 m

Answer :

Given: The area of the base of a rectangular tank is 6500 cm^{2}.

Volume of water contained in it is 2.6 m^{3}.

We know that Rectangular tank is in the shape of a cuboid.

And also area of the base of a cuboid is given by : l × b (here l and b are length and breadth respectively)

∴ l × b = 6500 cm^{2} ….1

Volume of a cuboid is given by: l × b × h (here l, b, h are length, breadth, height respectively)

∴ l × b × h = 2.6 m^{3} = 2.6 × 1000000 cm^{3} = 2600000 cm^{3} …2

From —1 and —2

6500 × h = 2600000

h = = 400 cm = m = 4m

∴ h = 4m

That is, depth of water in the tank is 4m
