Question

A powder tin has a cuboidal shape of measures 12cm x 12cm x 17.5cm. Another powder tin is cylindrical whose base diameter is 12cm and hieght is 17.5cm. Which powder tin has more capacity and by how much????

Answer 1

volume of cuboidal shape: lbh
                       powder tin   =12*12*17.5 cm³
                                             =2520 cm³
Volume of cylindrical shape :πr²h
powder tin                            =22/7 * 12/2*12/2*17.5
                                               =1980 cm³

volume of cuboidal shape-volume of cylindrical shape=2520-1980
                                                                                           =540 cm³

therefore cuboidal shape powder tin has more capacity
by 540 cm³
