1.	What is the density of a liquid of mass 20 kg, enclosed in a cuboid of surface areas of three sides as 1 m^2, 2 m^2, 5 m^2, and one of its sides is 2 m?(a) 1 kg/m^3(b) 2 kg/m^3(c) 3 kg/m^3(d) 4 kg/m^3I got this question at a job interview.Question is taken from Density topic in chapter Moles, Density & Concentration of Basic Chemical Engineering
Answer» Right answer is (b) 2 kg/m^3 Explanation: Sides of the cuboid are 1m, 2m and 5m, => VOLUME = 10 m^3, DENSITY = 20/10 = 2 kg/m^3.
