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