volume of cube = 1000 cubic cms.
a X a X a = 1000
a = 10 cm.
Side of the cube becomes the diameter of cone.
d = 10 cm
r = 5 cm
height is also equal to 10 cm.
volume of cone = (22/7)*r * r * (h/2) cubic cms.=22 * 5 * 5 * 10/21 = 261.9 cubic cms.

volume of cube is A³= 1000
there fore A = 10
since the cone is made from the cube the side will be diameter of the cone or radius will be 10/2=5
since height is 10 and radius is 5 the volume of the cone is 1/3 π r² h
1/3x22/7x5x5x10 =5500/21 =261.90
