Q. 25

A cubical ice-cre

Given: Cubical ice-cream brick of edge 22.

Ice-cream cone of radius 2 cm and height 7 cm.

Let ‘n’ be the number of students who get ice-cream cones.

Let V1 be the volume of the Cubical Ice-cream brick.

Volume of Cube is given by: a3 (where a is the edge length)

V1 = a3 = 223

Let V2 be the Volume of the Ice-cream Cone.

Volume of Cone is given by: × π × r2 × h (where r is the radius of the base and h is the edge height of the cone)

V2 = × π × r2 × h = × π × 22 × 7

Here,

V1 = n × V2

223 = n × × π × 22 × 7

n = = = 363

363 Children can get ice cream cones.
