Final Answer:
The volume of the prism is

Step-by-step explanation:
The formula for the volume (V) of a rectangular prism is given by
where (l) is the length, (w) is the width, and (h) is the height. In this case, the provided dimensions are length (l = 18), width (w = 9), and height (h = 4). Substituting these values into the formula:
Therefore, the volume of the prism is

Understanding the concept of volume in three-dimensional geometry is vital. The formula
reflects the relationship between the length, width, and height of a rectangular prism. Multiplying these dimensions provides the total space enclosed by the prism in cubic units. In this instance, with a length of 18 units, a width of 9 units, and a height of 4 units, the volume calculation yields
representing the spatial capacity of the given prism.
Calculating the volume of prisms is a fundamental skill in geometry and has practical applications in various fields, including architecture and engineering. This calculation allows us to quantify the amount of space a three-dimensional object occupies, providing essential information for design and analysis. In this case, the resulting volume,
represents the capacity of the rectangular prism specified by the given dimensions.
