1.	3.A farmer wants to dig well either in the formof cuboid of dimensions (1 m Ă 1 m Ă 7 m)or in the form of cylinder of diameter 1 mand height 7 m. The rate to dig the well isR450/m3. Find the cost to dig both wells.The farmer decides to dig the cylindricalwell. By his decision which value isdepicted?
Answer» V ofcuboidal well=lbh = 7 m³Rate = 7450 = 3150 Rs. V of cylindrical well = 5.5m³Rate = 5.5450 = 2475 Rs. Value depicted = Economical approach

Answer»

V ofcuboidal well=lbh = 7 m³Rate = 7*450 = 3150 Rs.

V of cylindrical well = 5.5m³Rate = 5.5*450 = 2475 Rs.

Value depicted = Economical approach
