Determine the area of the top of the rectangular prism

To determine the area of the top of a rectangular prism, you need to know the length and width of the top surface of the prism.

If the length of the top of the rectangular prism is given as L units and the width of the top of the prism is given as W units, then you can calculate the area of the top surface using the formula:

Area = Length x Width

Therefore, the area of the top of the rectangular prism is calculated by multiplying the length and width of the top surface together.
