Question
Q. :- There is an object its top and bottom surface area is 15 unit and it has constant hight of 5 unit. Find the volume of this object. The top surface is directely above the bottom surface.
-
Step : 1
Cut this object along hight in many pieces so that the top and bottom surface area of pieces are very-very small and the top surfaces are directely above the respective bottom surfaces.
Now arrange the smaller pieces so that the bottom of the arrangments becomes rectangular. The top and bottom surface area of this new shape (cuboid) is 15 unit.
-
Step : 2
The hight remains same as earlier. So hight = 5 unit
The volume of this cuboid = the volume of original object = 15 x 5 = 75 unit volume.
