Answer 1

To calculate the surface area of a pyramid, we need to know its base area and the area of its triangular faces. The formula for the surface area $S.A.$ of a pyramid with a base area $B$ and slant height $l$ for the triangular faces is:

$$S.A.=B+\frac{1}{2}\times P\times l$$

where $P$ is the perimeter of the base.

Since you haven't provided specific dimensions or types of pyramids, I cannot calculate the surface area directly. However, if you have those dimensions, you can plug them into the above formula to find the surface area.

If the options given (81.2 in², 96.8 in², 154.4 in², 122.4 in²) are responses based on certain calculations you have, please provide the dimensions or more details about the pyramid so I can assist you further in determining the correct surface area.
