Question

A talcum powder is available in two packs, a tin can with a square base of side 6cm and height 10cm and a tin can of circular base of radius 3.5cm and height 12cm. which of them has greater volume and by how much?​

Answer 1

here you know about the area of cross section of the tin plate which is a square. it will be (6) squared. now volume for the can will be = Area of cross section x height so calculating the volume we get (6) squared x 10 = 360cc (cubic centimeters).

now for the cylindrical can we have area of cross section {pi x( 3.5)squared}. now volume of cylinder equals {pi ×(3.5) squared} x height (12) = 66cc so the circular one has more volume.
