Ram a farmer, managed to grow shaped-watermelons inside glass cases of different shapes. The shapes he used were: a perfect cube, hemi-spherical, 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 water-melons would be equal irrespective of the shape.

A customer wants to buy water-melon for making juice, for which the skin of the water-melon has to be peeled off, and therefore is a waste. Which shape should the customer buy?
1.Cube
2.Hemi-sphere
3.Cuboid
4.Cylinder
5.Normal spherical

• i think answer is option 5, normal spherical,
  as the volume occupies by spherical is always maximum then any other shape
  
  cube = length^3
  cuboid = length*breadth*height , but it will be calculated as cube of smallest length
  cylinder = pi*r*r*h , here r= h
  sphere = (4/3)*pi*r^3
  hemisphere =(2/3) * pi*r^3
  
  it is clear that if the dimension is same for all then volume of sphere is maximum

• shape watermelon means, the shape of water melon is different or the cases shape are different ??
