Answer 1

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

Surface area of the top step:
Length: 14 in.
Width: 8.5 in.
Surface area = 2(14)(8.5) = 238 sq. in.

Surface area of the bottom step:
Length: 17 in.
Width: 13 in.
Surface area = 2(17)(13) = 442 sq. in.

Total surface area = 238 + 442 = 680 sq. in.

Therefore, the surface area of the 3D two-tiered steps is 680 sq. in.
