The calculated surface area of the rectangular prism is 82 square cm
Finding the surface area of the rectangular prism
From the question, we have the following parameters that can be used in our computation:
The net of the prism
The surface area of the net is then calculated as
Surface area = Area of rectangle + 2 * area of triangle
So, we have
Surface area = (3 + 4 + 5) * 6 + 2 * 1/2 * 5 * 2
Evaluate
Surface area = 82
Hence, the surface area of the net is 82 square cm
