The length of the side of a cube is 1.2 10⁻² ~m . Its volume up to correct significant figures is

Options

  1. A1.732 10⁻⁶ ~m ^3
  2. B1.73 10⁻⁶ ~m ^3
  3. C1.70 10⁻⁶ ~m ^3
  4. D1.7 10⁻⁶ ~m ^3

Correct answer

D. 1.7 10⁻⁶ ~m ^3

Step-by-step solution

Length of cube, 1=1.2 10⁻² ~m Volume =1^3= (1.2 10⁻² )^3=1.728 10⁻⁶ ~m ^3 The volume of cube upto correct significant figure is V =1.7 10⁻⁶ ~m ^3
