How many sack of dimension 15 cm × 45 cm × 90 cm filled with rice can be kept in a room of dimension 3 m × 18 m × 9 m
Advertisements
उत्तर
Number of sacks = `"Dimension of room"/"Dimension of sacks"`
= `(3 "m" xx 18 "m" xx 9 "m")/(15 "cm" xx 45 "cm" xx 90 "cm")`
= `(300 "cm" xx 1800 "cm" xx 900 "cm")/(15 "cm" xx 45 "cm" xx 90 "cm")`
= 4 × 200 × 10
= 8000 sacks
