If the volume of a cube is 27 m^{3}, find its surface area (in m2) .
24
54
27
9
To find the surface area of the cube given its volume:
- Volume of a cube formula: \( V = a^3 \), where \( a \) is the side length.
- If the volume is 27 m\(^3\), then \( a^3 = 27 \).
- Solving for \( a \): \( a = \sqrt[3]{27} = 3 \) m.
- Surface area of a cube formula: \( \text{Surface Area} = 6a^2 \).
- Substituting \( a = 3 \) m:
- Surface Area = \( 6 \times (3)^2 \)
- Surface Area = \( 6 \times 9 = 54 \) m\(^2\).
- Option 1: 24 m\(^2\) – Incorrect
- Option 2: 54 m\(^2\) – Correct
- Option 3: 27 m\(^2\) – Incorrect
- Option 4: 9 m\(^2\) – Incorrect
