a farmer want to dig a well either in the form of cuboidal shape of 1.5m *1.5m* 7mor in the cylindrical shape of radius 75cm and and hieght 7m the rate of digging a well is RS 75per m cube the farmer decided to dig cylindrical form of well 1)calculate the coast to dig the well in both case 2)by the decesion what value is depicted by the farmer?
Volume of cuboid=lbh
=1.5*1.5*7=15.75m^3
Volume of cylinder=πr^2h
=π*75*75*700/10^6=12.375m^3
Cost=15.75*75/100=RS 11.81(Cuboid)
Cost=12.37*75/100=RS 9.28(Cylinder)
Hence Farmer made a great choice in selecting cylinderical tank as it is less expensive.
