The surface area of the trapezoidal prism is 385.6 square yard
Calculating the surface area of the trapezoidal prism.
From the question, we have the following parameters that can be used in our computation:
The trapezoidal Prism.
The total area of the trapezoidal Prism is the sum of the individual shapes
So, we have
Surface area = 2 * trapezoid area + 2 * small rectangles + Big rectangle + Smallest rectangle
Using the above as a guide, we have the following:
Surface area = 2 * 1/2 * (6 + 10) * 4.6 + 2 * 5 * 12 + 10 * 12 + 6 * 12
Evaluate
Surface area = 385.6
Hence, the total area of the figure is 385.6 square yard
