The approximate volume of a cube of side a meters on increasing the side by 4% is:
- A \(1.04 a^3 m^3\)
- B \(1.004 a^3 m^3\)
- C \(1.12 a^3 m^3\)
- D \(1.12 a^2 m^3\)
Answer & Solution
Correct Answer
(C) \(1.12 a^3 m^3\)
Step-by-step Solution
Detailed explanation
New side \( = a(1 + 0.04) = 1.04a \) New volume \( = (1.04a)^3 = (1.04)^3 a^3 = 1.124864 a^3 \) Approximate volume \( = 1.12 a^3 m^3 \)
