To calculate the surface area of a puzzle game represented by square units of 1 inch each, we need to know how many squares are involved in the design. However, since the question does not provide specific information about the arrangement or dimensions of the object, I can't determine an exact surface area value directly.
If you assume a puzzle game that consists of 54 individual squares (since "54 in." is one of the multiple-choice options), the surface area would indeed be 54 square inches. Therefore, if that is the case, the answer would be:
54 in.²
If you have more specific details about the dimensions or layout of the puzzle game, please provide them for a more accurate calculation.
