The number of children who will get the ice cream cones.

A cubical icecream brick of edge 22 cm is to be distributed among some children by filling icecream cones of radius 2 cm and height 7 cm upto its brim. The number of children who will get the ice cream cones is
(a) 163
(b) 263
(c) 363
(d) 463

Solution:

Edge of a cubical icecream brick = 22 cm
Volume = a³ = (22)³ = 10648 cm³
Radius (r) of ice cream cone (r) = 2 cm
and height (h) = 7 cm

Twelve solid spheres of the same size are made by melting a solid metallic cylinder of base diameter 2 cm and height 16 cm. The diameter of each sphere is
(a) 4 cm
(b) 3 cm
(b) 2 cm
(d) 6 cm

Solution:

Diameter of cylinder = 2 cm
Radius = = 1 cm
and height = 16 cm
