Answer:Surface Area of a Solid
The surface area of a 3-dimensional object is the measure of the total area of all its faces. This means that one way to find the surface area of a solid is to find the area of its net. The surface area of a rectangular prism is the area of the six rectangles that cover it.
Step-by-step explanation:
Answer:
Total surface area = 580.96 yd^2
Step-by-step explanation:
Total surface area
From left to right
Rectangle 1
A = lw = 9.9 *20 =198
Rectangle 2
A = lw = 6.8 *20 =136
Rectangle 3
A = lw = 9.9 *20 =198
Triangle top
A = 1/2 bh = 1/2 (6.8)(7.2) =24.48
Triangle bottom
A = 1/2 bh = 1/2 (6.8)(7.2) =24.48
Add them together
198+136+198+24.48+24.48
580.96
Total surface area = 580.96 yd^2
