1.	For 2.5 cm c.c. floor for 100 sq m of area and 10% for contingency what amount of cement concrete will be required?(a) 5.75 cu m(b) 2.75 cu m(c) 2.5 cu m(d) 5.0 cu mI got this question by my college professor while I was bunking the class.Question is taken from Analysis of Rates of Cement Concrete in division Analysis of Rates of Civil Engineering Drawing
Answer» Right option is (b) 2.75 cu m Best explanation: For 2.5 cm c.c. floor for 100 sq m of area the quantity of CEMENT concrete = 100*.025 = 2.5 cu m. Adding 10% extra for unevenness of BASE concrete, the quantity comes to 2.5+.25 = 2.75 cu m.
