Step-by-step explanation:

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

To find :

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

(ii) The cost of sheet for it, if a sheet measuring 7m×3.5m costsर 510.

Solution :

i) The dimension of the box is

Length l= 1.5 m

Breadth b= 1.25 m

Height h= 65 cm = 0.65 m

Area of the sheet required is

The area of the sheet required for making the box is 5.45 meter square.

ii) The cost of sheet for it, if a sheet measuring 7m×3.5m costsर 510.

i.e, area of sheet 24.5 meter square cost Rs.510

So, 1 meter square cost

Now, The cost of 5.45 meter square cost

Therefore, The cost of sheet is Rs. 113.447.

Given: Length of box =1.5 m, Breadth =1.25 m, Height =0.65 m ⇒Area to be white-washed = Area of cuboid − Area of base. (i) Area of sheet requred =2lb+2bh+2lh−lb (i) Area of sheet requred =2lh+2bh+lb .....[Box is open] =[2×1.5×0.65+2×1.25×0.65+1.5×1.25] m 2 =(1.95+1.625+1.875)m 2 =5.45 m 2 ii) Cost of sheet per m 2 area = Rs. 20 Cost of sheet of 5.45m 2 area = Rs. 5.45× HOPE this helps u dear...
