### Instruction: A rectangular pool is $6\text{ m}$ wide, $12\text{ m}$ long and $4\text{ m}$ deep. If the pool is half full of water, what is the volume of water in the pool?### Response: I know that the volume of a rectangular prism is the product of its length, width and height.
So, the volume of the pool when it is full of water is $6\times 12\times 4=288\text{ m}^3$.
If the pool is half full of water, then the volume of water is half of that, or $\frac{1}{2}\times 288=144\text{ m}^3$.
