We are given a figure and we are asked to determine its volume. The given figure is a straight prism, therefore, the volume is given by:
![V=A_bh](https://img.qammunity.org/2023/formulas/mathematics/college/d4d9f4gr2q4ka2iprvi7z5b81j83wbuf06.png)
Where:
![\begin{gathered} A_b=\text{ area of the base} \\ h=\text{ height} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ywmxvgriq959b5r9rkqjp4jcw8jhjlrhuq.png)
Substituting the values we get:
![V=(20\operatorname{cm})(5\operatorname{cm})]()
Solving the operation:
![V=100\operatorname{cm}^3]()
Therefore, the volume of figure A is 100 cubic centimeters. The same procedure can be used to determine the volume of figure B.
