The volume prism refers to the number of cubic units that will exactly fill the figure. The volume of a rectangular prism can be found or calculate by using the formula V=Bh, where B represents to the area of the base or in other words the length and width of the rectangle.
In this exercise is given that a stack of newspapers in the shape of a prism is 12 inches long, 10 inches wide, and 12 inches tall. It is asked to find its volume. In order to find the volume of the prism, you should substitute the given values into the previous mention formula.
V=Bh V=(10 in)(12 in)(12 in) V=1440 in^3
The volume of the stack of newspapers is 1440 cubic inches.
