Wax with dimensions 70 cm, 44 cm, and 20 cm to prepare cylindrical candles, each 14 cm in diameter and 20 cm in height.
Formula Used:
Volume of cuboid = length × width × height
Volume of cylinder = π × (radius)2 × height
Calculation:
Volume of cuboid = 70 × 44 × 20
⇒ Volume of cuboid = 61600 cm3
Volume of one candle = 22/7 × (7)2 × 20
⇒ Volume of one candle = 22 × 140
⇒ Volume of one candle = 3080 cm3
Number of candles = Volume of cuboid / Volume of one candle
⇒ Number of candles = 61600 / 3080
⇒ Number of candles = 20
∴ The correct answer is option (1).
