Pool Water Height

A 1-meter-wide sidewalk will be paved around the block-shaped pool in the garden. The dimensions of the bottom of the pool are 8.5 meters and 6 meters. The height of the pool walls is 2 meters. There are 86.7 m³ of water in the pool. How high did the water reach?

Final Answer:

h =  1.7 m

Step-by-step explanation:

$$\begin{gathered} a=8.5\text{m} \\ b=6\text{m} \\ V=86.7{\text{m}}^3 \\ S=a\cdot b=8.5\cdot 6=51{\text{m}}^2 \\ h=V/S=86.7/51=1.7\text{m} \end{gathered}$$
