Find the surface area
A = 2.3×2.3×2 + 2.3×6.1×2 + 2.3×6.1×2
Answer:
80 ft²
Step-by-step explanation:
From the diagram
The umbrella has a total of 8 triangle.
Applying
A = 8(bh)/2
A = 4bh...................... Equation 2
Where A = Amount of fabric, b = base of one of the triangle in the octagonal pyramid, h = height of the triangle.
From the diagram,
Given: b = 4 ft, h = 5 ft
Substitute these values into equation 2
A = 4×4×5
A = 80 ft²
