Question

a conical solid block is exactly fitted inside the cubical box of side 'a' ,then the volume of conical solid block is

Answer 1

when it is exactly fitted then radius (r)= a/2
and height h= a
so volume =1/3*22/7*a/2*a/2*a
=33a³/7 units ³

Answer 2

Answer:1/12πa³

Step-by-step explanation:

When a conical block is exactly fitted inside a cubical block its height = diameter = side of the cubical block = a units.

So r = d/2

= a/2

So volume of cone = 1/3πr²h

= 1/3*π*(a/2)² * a

= 1/3*π*a²/4*a

= 1/12*πa³
