1. A plastic box 1.5 m long. 1.25 m wide and 65 cm deep is to be made.

1.	1. A plastic box 1.5 m long. 1.25 m wide and 65 cm deep is to be made. It is opened at thetop. Ignoring the thickness of the plastic sheet, determine:(1) The area of the sheet required for making the box.(ii) The cost of sheet for it. if a sheet measuring Im costs 20.
Answer» ANSWER: (i) 3.75m (II)Rs75 Step-by-step EXPLANATION: TOTAL SURFACE area of a cuboid = 2(lb+bh+hl) we consider the the height as 0 as they said to ignore the thickness. 2(1.5x1.25)= 3.75 3.75x20=75

Answer»

(i) 3.75m

(II)Rs75

Step-by-step EXPLANATION:

TOTAL SURFACE area of a cuboid = 2(lb+bh+hl)

we consider the the height as 0 as they said to ignore the thickness.

2(1.5x1.25)= 3.75

3.75x20=75
