The edge of the cubical ice - cream brick = a = 22 cm

Volume of the cubical ice - creaam brick = (a)

`= (22xx22xx22) "cm"^3`

Radius of an ice- cream cone = 2 cm

Height of an ice - cream cone = 7 cm

Volume of each ice - cream cone `= 1/3pi"r"^2"h" `

`= (1/3xx22/7xx2xx2xx7) "cm"^3`

Number of ice - cream cones`= "Volume of the cubical ice cream brick"/"Volume of each ice cream cone"`

`= (22xx22xx22xx3xx7)/(22xx2xx2xx7)`


Hence, the number of ice cream cones is 363
