Final answer:
The volume of a rectangular prism is represented by the expression lwh, where l is the length, w is the width, and h is the height.
Step-by-step explanation:
The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height. To determine which expression represents the volume of the given rectangular prism, we need to consider the formula. The correct expression is d) lwh because it includes all three variables and follows the formula for the volume of a rectangular prism.
