Centimeters 6989

The pool measures 4 m and 3 m, and 2.5 m. What height does the water in the pool reach if 25 m³ of water has been added? Round the result to centimeters.

Correct answer:

x =  208 cm

Step-by-step explanation:

$$\begin{gathered} a=4\text{m} \\ b=3\text{m} \\ c=2.5\text{m} \\ V=25{\text{m}}^3 \\ S=a\cdot b=4\cdot 3=12{\text{m}}^2 \\ {c}_1=V/S=25/12=\frac{25}{12}\doteq 2.0833\text{m} \\ {c}_1<c \\ x=c_1\to \text{cm}=c_1\cdot 100\text{cm}=2.0833\cdot 100\text{cm}=208\text{cm}=208\text{cm} \end{gathered}$$
