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.
