The surface area of the rectangular prism is 997.88 square mm
Calculating the surface area of the figure
From the question, we have the following parameters that can be used in our computation:
The rectangular prism
The total area of the rectangular prism is calculated using
Surface area = lh + (a + b + c)h
Where
l and h are the base and height of the
So, we have
Area = 13.3 * √[20.5² - 13.3²] + (13.3 + √[20.5² - 13.3²] + 20.5) * 16
Evaluate
Area = 997.88
Hence. the total area of the figure is 997.88 square mm
