Question

A plastic box 1.5 m long, 1.25 m wide and 65 cm deep is to be made. It is to be open at the top. Ignoring the thickness of the plastic sheet, determine:

(i) The area of the sheet required for making the box.

(ii) The cost of sheet for it, if a sheet measuring 1m2 cost Rs.20.

​

Answer 1

Answer:

lateral surface area of plastic box+ lb = 2(l+b)×h +lb

2(1.5+1.25)×0.65 + 1.5×1.25

=2.2750+1.875=4.1500 m^2

Now, cost = 4.1500×20 = 83.0000=83
