Answer:

The area of one of the triangular faces is;

Step-by-step explanation:

Given the diagram in the attached image.

We want to calculate the area of the triangular face.

Recall that the area of a triangle can be calculated using the formula;

Given;

$\begin{gathered} b=3in \\ h=\sqrt[]{5^2-3^2}=\sqrt[]{25-9}=\sqrt[]{16} \\ h=4in \end{gathered}$

Substituting the values;

$\begin{gathered} A=(1)/(2)*3in*4in \\ A=6in^2 \end{gathered}$

The area of one of the triangular faces is;
