  • C. 100 square centimeter
  • D. 1 square meter
Correct Answer: Option C - The degree of accuracy in calculations depends upon the rate of item of work. The rate are Per m, sq.m, cu.m, arithmetic calculation should be carried out up to two places of decimal for greater accuracy at higher rate. Method of measurement according to IS 1200 : 1983– • Dimensions (Length, breadth, height) shall be measured to the nearest 0.01 meter (or 1cm). • Area shall be measured to the nearest 0.01 sq.m or (100 sq.cm). • Cubic or volume contents shall be worked out to the nearest 0.01 cu. metre.
