Calculate Surface Area: Cube with 12 cm Edges

To solve for the surface area of the cube, follow these steps:

• Step 1: Identify the given information. The edge length of the cube is 12 cm.
• Step 2: Apply the surface area formula for a cube, which is $A = 6s^2$, where $s$ is the side length.
• Step 3: Substitute the side length into the formula: $A = 6 \times 12^2$.
• Step 4: Calculate $12^2 = 144$.
• Step 5: Multiply the result by 6: $A = 6 \times 144 = 864$.

Therefore, the surface area of the cube is $864 \, \text{cm}^2$.
