To calculate the surface area of a two-tiered step structure, we need to know the dimensions of each tier (length, width, height) and the number of sides exposed. Without the image or specific dimensions, I can't provide an exact surface area.
However, if you have the dimensions and layout for the two tiers, you can compute the surface area as follows:
-
Identify the dimensions of each tier (L1, W1, H1 for the first tier; L2, W2, H2 for the second tier).
-
Calculate the area of all exposed surfaces:
- For the top of each tier, use \(L \times W\).
- For the sides of each tier, calculate accordingly (sides that are exposed).
-
Add the areas together for total surface area.
Once you have all the areas calculated, you can compare them to the provided responses to find the correct one.
If you provide me with those dimensions or characteristics of the steps, I could help you compute the surface area!
