A woodcutter desires to make dusters for schools. he plans to make dusters of dimensions 10cm x 4cm x 3cm. How many dusters can be made from a wooden plank of dimensiions 4m x 3m x 1m?
No. of dusters = 400 cm* 300 cm * 100 cm / ( 10 cm * 4 cm * 3 cm)
= 100000
Ans: 100000 dusters
Cheers
Best of Luck
