The surface area of the triangular prism is 108 square cm
Calculating the surface area of the triangular prism.
From the question, we have the following parameters that can be used in our computation:
The Triangular Prism.
The total area of the Triangular Prism is the sum of the individual shapes
So, we have
Surface area = 2 * triangle area + area of big rectangle
Using the above as a guide, we have the following:
Surface area = 2 * 1/2 * 4 * 3 + (4 + 3 + 5) * 8
Evaluate
Surface area = 108
Hence, the total area of the figure is 108 square cm
