The formula to calculate the lateral area of a prism is:
\[ LA = P \times h \]
Where:
The lateral area of a prism is the sum of the areas of its lateral faces, which are the faces that connect the bases of the prism. It does not include the areas of the bases themselves. In other words, it is the surface area of the prism excluding the top and bottom. The formula to calculate the lateral area of a prism is the perimeter of the base times the height of the prism.
Let's assume the following values:
Step 1: Calculate the Lateral Area (LA):
\[ LA = P \times h = 20 \times 15 = 300 \text{ square units} \]
The lateral area is 300 square units.
