Find the surface area of the two-tiered steps

(1 point)

1 ,171.5 ln.^ 2

, 400.5 ln.^ 2

879In .^ 2

2 ,320.5 ln.^ 2

Answer 1

To find the surface area of the two-tiered steps, we need to calculate the surface area of each tier separately and then add them together.

Let's say the surface area of the first tier is A1 and the surface area of the second tier is A2.

A1 = 500 ln.^2
A2 = 320 ln.^2

Total surface area = A1 + A2
Total surface area = 500 ln.^2 + 320 ln.^2
Total surface area = 820 ln.^2

Therefore, the surface area of the two-tiered steps is 820 ln.^2.

So, the closest option is 879In .^ 2.
