A cube has a side of 1.2 x 10^-2m. Its volume will be recorded as:
Correct answer: C. 1.7 x 10^-6 m3
- A. 1.728 x 10^-6 m3
- B. 1.72 x 10^-6 m3
- C. 1.7 x 10^-6 m3
- D. 0.72 x 10^-6 m3
Explanation
The following is the solution: Volume=l3=1.728x10-6m3 The length has two significant figures, hence v = 1.7x10-6 m3
