The formula for calculate the volume of a rectangular prism is shown below:
Where "l" is the length, "w" is the width and "h" is the height.
In this case you can identify that:
![\begin{gathered} l=4\operatorname{cm} \\ w=2\operatorname{cm} \\ h=5\operatorname{cm} \end{gathered}]()
Then, you can substitute these values into the formula:
![V=(4\operatorname{cm})(2\operatorname{cm})(5\operatorname{cm})]()
Finally you must evaluate, in order to find the volume of this rectangular prism:
![V=40\operatorname{cm}^3]()
The answer is:
![40\operatorname{cm}^3]()
