Answer:
Step-by-step explanation:
It is easy to find the sheet required to make such a box
We have to find its CSA and subtract it by area of the sheet where the box is open.
CSA = 2*(lb+bh+hl)
=2* (2.5*2+2*1+1*2.5)
=2*(54.5 )
=109 m^2
Area of the sheet which is not being used (i.e the side left open)
=l*b =2.5*2=5m^2
CSA -lb = 109 -5 = 104m^2
Therefore 104m^2 is the area of the sheet required to make the box.
