The correct Answer is:
To find the volume of the cube given its total surface area, we can follow these steps: ### Step 1: Understand the formula for the total surface area of a cube. The total surface area (TSA) of a cube is given by the formula: \[ \text{TSA} = 6 \times \text{side}^2 \] ### Step 2: Set up the equation using the given total surface area. We know from the problem that the total surface area of the cube is \(96 \, \text{cm}^2\). Therefore, we can set up the equation: \[ 6 \times \text{side}^2 = 96 \] ### Step 3: Solve for the side length of the cube. To find the side length, we first divide both sides of the equation by 6: \[ \text{side}^2 = \frac{96}{6} \] Calculating the right side: \[ \text{side}^2 = 16 \] ### Step 4: Take the square root to find the side length. To find the side length, we take the square root of both sides: \[ \text{side} = \sqrt{16} \] Calculating the square root: \[ \text{side} = 4 \, \text{cm} \] ### Step 5: Calculate the volume of the cube. The volume (V) of a cube is given by the formula: \[ V = \text{side}^3 \] Substituting the side length we found: \[ V = 4^3 \] Calculating \(4^3\): \[ V = 4 \times 4 \times 4 = 16 \times 4 = 64 \, \text{cm}^3 \] ### Final Answer: The volume of the cube is \(64 \, \text{cm}^3\). ---
