How many envelopes can be made out of a sheet paper 3 metre 24 cm by 1 metre 72 CM . if each envelopes requires a piece of paper size 18 cm by 12 CM ???

Answer 1

let the length L of the sheet=3.24m
breadth b=1.72m
area of the rectangular sheet =1.72x3.24=5.573sq.m
let n be the number of envelope tobe made out of the sheet of area =5.573sq.m
length and breadth of the envelope are 18cm and 12cm
l=18/1000=0.18m and b =12/1000=0.12
nx area of the envelope =5.573
nx0.18x0.12=5.573
0.0216n=5.573
n=5.573/0.0216
n=258 (approx)
