In previous grades, you learned that the volume, or amount of space of a three-dimensional figure can be determined by counting the number of cubic units that will fit inside the figure. In particular, if you have a right rectangular prism, or a prism whose bases are rectangles and whose lateral faces are perpendicular to both bases, you can use the formula V = Bh, where B represents the area of the base and h represents the height of the prism.

In this lesson, you will use volume formulas to solve application problems. In doing so, you will solve problems that include fractions and decimals, so you may need to review multiplication and division of fractions. You may also need to review how to convert between fractions and decimals in order to perform computations with rational numbers.
