Given:
The given figure is a rectangular prism.
The length of the rectangular prism is 42 inches.
The width of the rectangular prism is 33 inches.
The height of the rectangular prism is 20 inches.
We need to determine the volume of the rectangular prism.
Volume of the rectangular prism:
The volume of the rectangular prism can be determined using the formula,
![V=length * width * height](https://img.qammunity.org/2021/formulas/mathematics/college/ou1bnnxhtmq3ogha2tqb5px73lljizmjvj.png)
Substituting the values, we get;
![V=42 * 33 * 20](https://img.qammunity.org/2021/formulas/mathematics/college/cy29hmgmbqnleiaphy5pni9u4p81ksbpiw.png)
Multiplying, we get;
![V=27720 \ in^3](https://img.qammunity.org/2021/formulas/mathematics/college/xn5zz8ozib8npmbw4g62whqub2qjayt7y4.png)
Thus, the volume of the rectangular prism is 27720 cubic inches.
