Hectoliters 48941

The pool has dimensions: a length of 50 m, a width of 15 m, and a depth of 2 m. It is filled with water to 1/4 of its depth. How many hectoliters of water are in the pool? How many hectoliters of water can fit in a filled pool?

Correct answer:

V₁ =  3750 hl
V =  15000 hl

Step-by-step explanation:

$$\begin{gathered} a=50\text{m} \\ b=15\text{m} \\ c=2\text{m} \\ q=\frac{1}{4}=0.25 \\ {V}_0=a\cdot b\cdot c=50\cdot 15\cdot 2=1500{\text{m}}^3 \\ V=V_0\to \text{hl}=V_0\cdot 10\text{hl}=1500\cdot 10\text{hl}=15000\text{hl} \\ {V}_1=q\cdot V=\frac{1}{4}\cdot 15000=\frac{1\cdot 15000}{4}=\frac{15000}{4}=3750\text{hl} \end{gathered}$$
