The correct Answer is:
To find the total surface area of a cube when the side length is given, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the side length of the cube**: The side length of the cube is given as \( 2\sqrt{3} \) cm. 2. **Recall the formula for the total surface area of a cube**: The total surface area (TSA) of a cube can be calculated using the formula: \[ \text{TSA} = 6 \times (\text{side length})^2 \] 3. **Substitute the side length into the formula**: Substitute \( 2\sqrt{3} \) cm into the formula: \[ \text{TSA} = 6 \times (2\sqrt{3})^2 \] 4. **Calculate \( (2\sqrt{3})^2 \)**: First, calculate \( (2\sqrt{3})^2 \): \[ (2\sqrt{3})^2 = 2^2 \times (\sqrt{3})^2 = 4 \times 3 = 12 \] 5. **Multiply by 6**: Now, substitute back into the TSA formula: \[ \text{TSA} = 6 \times 12 = 72 \text{ cm}^2 \] 6. **Final Answer**: The total surface area of the cube is \( 72 \text{ cm}^2 \).
