Given: Side of a cube = 6 cm Formula used: Volume of a cube = (side)3 Volume of a cone = (
1
3
) × π × r2 × h Calculation: Maximum cone which can formed by cube Height of cone = 6 cm Radius of cone = 3 cm Volume of cone = (
1
3
) × π × (3)2 × 6 ⇒ 18π Volume of a cube = (6)3 ⇒ 216 Waste part of a cube = Volume of a cube – Volume of a cone ⇒ 216 - 18π Ratio of waste part to the cone = [
