Volume of a bucket
« on: February 20, 2013, 11:16:47 am »
Question : An open metallic bucket is in the shape of a frustum of a cone mounted on a hollow cylindrical base of metallic sheet. If the diameters of the two circular ends of the bucket are 45 cm and 25 cm, the total vertical height of the bucket is 30 cm and that of the cylindrical portion is 6 cm, find the area of the metallic sheet used to make the bucket. Also, find the volume of water it can hold.

My question is that if the bucket is indeed open, then it has zero capacity, logically thinking, because it can hold no water ?  :scratchchin:

If you press the open side against the floor, such that there is no space between the bucket and the floor, then the bucket can contain water and have capacity.
Keep an open mind, but not so much that your mind falls out!!!
