1.	A plastic box 1.5 m long. 1.25 m wide and 65 cmdeep is to be made.it is opened at top.ignoring the thickness of the plastic sheet, determine:The area of the sheet required for making the box.The cost of sheet for it, if a sheet measuring 1m^2costs Rs 20.m and 3 m respectively
Answer» ANSWER: length=1.5m Breadth=1.25m Height=65cm =0.65m TSA of the CUBOID EXCLUDING the top=2(bh+lh)+lb =2(1.250.65+1.50.65)+1.51.25 =2(0.8125+0.975)+1.975 =21.7875+1.975 =5.45m square Cost of SHEET for 1M square=Rs20 Cost of sheet for 5.45m square=5.45*20 =Rs109

Answer»

ANSWER:

length=1.5m

Breadth=1.25m

Height=65cm =0.65m

TSA of the CUBOID EXCLUDING the top=2(bh+lh)+lb

=2(1.25*0.65+1.5*0.65)+1.5*1.25

=2(0.8125+0.975)+1.975

=2*1.7875+1.975

=5.45m square

Cost of SHEET for 1M square=Rs20

Cost of sheet for 5.45m square=5.45*20

=Rs109
