Question

find the lateral surface area of the prism. lsa =? cm²

Explanation:

Step1: Find the perimeter of the base triangle

The base triangle has sides \(5\) cm, \(5\) cm, and \(6\) cm.
\(P = 5 + 5+6=16\) cm.

Step2: Use the formula for lateral surface area of a prism

The formula for the lateral surface area (\(LSA\)) of a prism is \(LSA = P\times h\), where \(P\) is the perimeter of the base and \(h\) is the height of the prism. Here, \(h = 8\) cm.
\(LSA=16\times8\)
\(LSA = 128\) \(cm^{2}\)

Answer:

\(128\)
