Ram a farmer, managed to grow shapedwatermelons inside glass cases of different shapes. The shapes he used were: a perfect cube, hemispherical, cuboid, cylindrical along with the normal spherical shaped watermelons. Thickness of the skin was same for all the shapes. Each of the glass cases was so designed that the total volume and the weight of the all the watermelons would be equal irrespective of the shape.
