The floor of a rectangular swimming pool has an area of 350 sq. meters, and every point on the floor is of equal depth. If 4,200 cubic meters of water is poured into the pool, how deep will the water level be?

The depth is 12m

Step-by-step explanation:

The area is 350m^2

And the depth in each point of the base is at the same depth D.

Then we have a cuboid.

Now, the volume of a cuboid is equal to:

V= L*W*D

L = lenght, W = width and D = depth.

Such that L*W = area = 350m^2

then we have:

V = D*350m^2

Now we want V = 4200m^3

4200m^3 = D*350m^2

D = (4200/350) m = 12m

The depth is 12m
