Question

find the surface
area of the
triangular pyramid.
first, find the area of
one triangular side.
(area = bn+2)
area of one side: ? cm²

Explanation:

Step1: Substitute the values into the formula

The formula for the area of a triangle is \(A=\frac{bh}{2}\). Here, \(b = 6\) cm and \(h=6\) cm.
So, \(A=\frac{6\times6}{2}\).

Step2: Calculate the area

First, calculate \(6\times6 = 36\). Then, \(\frac{36}{2}=18\).

Answer:

\(18\)
