andrezito [222]

Volume is Length x Width x height.

The pool is cubical, so the length and width are the same dimension.

First find the volume of the pool that is filled by water:

Volume = 12 x 12 x 2 = 288 cubic meters.

Now convert cubic meters to liters:

1 cubic meter = 1,000 liters

288 x 1000 = 288,000 liters

olga nikolaevna [1]

Answer:

Height of the stone face = 66.29 feet

Step-by-step explanation:

Refer the given figure, here we need to find height of the stone face,

Height of the stone face = CD

CD = AD - AC

In ΔABC we have

$tan31=\frac{AC}{AB}\\\\tan31=\frac{AC}{900}\\\\AC=540.77feet$

In ΔABD we have

$tan34=\frac{AD}{AB}\\\\tan34=\frac{AD}{900}\\\\AD=607.06feet$

CD = AD - AC = 607.06 - 540.77 = 66.29 feet

Height of the stone face = CD = 66.29 feet
