We are given that a pool that has a rectangular prism shape has a volume of 200 cm^3. We would like to fill the pool to 95% of its capacity therefore, the volume is obtained by taking the 95% of 200. We do that like this:
[tex]200\times\frac{95}{100}[/tex]Solving the operation we get:
[tex]200\times\frac{95}{100}=190[/tex]Therefore, the amount of water must be 190 cm^3.
