Question

a box of dimensions(2.5m*2m*1m) is to be made , determine the area of the sheet require when the box is open at the top

Answer 1

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.
