The correct Answer is:
To find the total surface area of a cube when the area of one face is given, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the properties of a cube**: A cube has 6 faces, and each face is a square. The area of a square is calculated using the formula: \[ \text{Area} = \text{side} \times \text{side} = a^2 \] where \( a \) is the length of one side of the square. 2. **Identify the area of one face**: According to the problem, the area of one face of the cube is given as \( 10 \, \text{cm}^2 \). Therefore, we can write: \[ a^2 = 10 \] 3. **Calculate the total surface area of the cube**: The total surface area (TSA) of a cube is given by the formula: \[ \text{TSA} = 6 \times (\text{Area of one face}) = 6a^2 \] Since we know \( a^2 = 10 \): \[ \text{TSA} = 6 \times 10 = 60 \, \text{cm}^2 \] 4. **Final answer**: Therefore, the total surface area of the cube is: \[ \text{Total Surface Area} = 60 \, \text{cm}^2 \]
