The error in the measurement of length and mass of a cube is 3% and 4% respectively. The error in the measurement of its density will be

Options

  1. A13 %
  2. B6 %
  3. C9 %
  4. D15 %

Correct answer

A. 13 %

Step-by-step solution

Density of a cube is given by = M V = M L^3 The maximum percentage error in density is 100 = M M 100 + 3 ( L L 100 ) Given M M 100 = 4 % and L L 100 = 3 % 100 = 4 % + 3(3 %) = 4 % + 9 % = 13 % Answer: 13 %
