Hectoliters 4550

The water's surface in the pool is a rectangle 50 meters long and 12 meters wide. The water depth rises evenly from 1 meter at one end of the pool to 3 meters at the other end of the pool (longer sides). Determine the amount of water in the pool in hectoliters.

Correct answer:

V =  12000 hl

Step-by-step explanation:

$$\begin{gathered} a=50 \\ b=12 \\ {c}_1=1 \\ {c}_2=3 \\ c=(c_1+c_2)/2=(1+3)/2=2 \\ {V}_1=a\cdot b\cdot c=50\cdot 12\cdot 2=1200 \\ V=V_1\cdot 10=1200\cdot 10=12000\text{hl} \end{gathered}$$
