ANSWER
Total S.A of bigger box
=2(lb+bh+lh)
=2(25×20+25×5+20×5) cm
2
=2(500+125+100)
=1450 cm
2
⇒For overlapping extra area required =
450×5 /100
=72.5 cm²
∴ Total S.A (including overlaps)
=1450+72.5=1522.5 cm ²
Area of cardboard sheet for 250 such boxes
=(1522.5×250) cm
Total S.A of smaller box
=2(15×12+15×5+12×5)cm ²
=630 cm²
For overlapping area required =
630×5 /100
=31.5 cm²
Total S.A (including overlaps)=630+31.5=661.5 cm²
Area of cardboard sheet required for 250 such boxes
=250×661.5cm ²
=165375 cm ²
Total cardboard sheet required =380625+165375
=54000 cm ²
⇒Cost of 1000 cm²
cardboard sheet = Rs.4
⇒Cost of 546000 cm² cardboard sheet
= Rs.
546000×4 /1000
= Rs. 2184
