To find the surface area of the Rubik’s cube, we first need to determine the dimensions of the cube. A standard Rubik's cube is made up of 3x3 smaller squares on each face. Since each smaller square measures 1 inch, the side length of the entire cube is:
\[ \text{Side Length} = 3 \text{ squares} \times 1 \text{ inch/square} = 3 \text{ inches} \]
The surface area \( A \) of a cube is calculated using the formula:
\[ A = 6 \times (\text{side length})^2 \]
Plugging in the side length we found:
\[ A = 6 \times (3 \text{ inches})^2 = 6 \times 9 \text{ in}^2 = 54 \text{ in}^2 \]
Thus, the surface area of the Rubik's cube is:
54 in²
So the correct response from the options provided is:
54 in² or 54 in. squared.
