EXPLANATION
The prism shown is a rectangular prism or cuboid.
The volume of a cuboid is given by:
![Volume=l * b * h](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gj4gkf091udw1sx9ur0m147a4vn2j7gek8.png)
From the diagram, the length is l=15cm ,the breadth is b=10cm and the height is h=3cm.
We substitute the values into the formula to obtain,
![Volume=15 * 10 * 3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/44bpu67sy1087bw4tsufipqif0zrptj8pm.png)
We simplify to get,
![Volume=450 {cm}^(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4fiudialt9xg1y327ttxzuhecfv1napdij.png)
