Open hopper cars are a type of freight car used to move coal across Canada. The bottom dump doors allow coal to be easily unloaded. How can you use your understanding of composite figures to estimate the capacity of each car? What objects can you identify that create the hopper cars in the photograph?
In this lesson you investigated composite figures and methods for determining each figure’s volume and capacity. You applied the formulas for the volume and capacity of common geometric figures to solve a variety of practical problems, such as manipulating volume formulas to solve for dimensions.
