## Elementary Geometry for College Students (5th Edition)

This figure is a pentagonal prism. The formula for the volume of a prism is base area $\times$ hight. To find the base area you use the formula $\frac{1}{2}$ans where a is the apothem, n is the number of sides, in this case 5, and s is the side length which in this case is 9.2. Once you find the base area of the prism you multiply it by the height 14.6 in this case and you get your answer 2115.54.
