250*2*(30*20+20*20+20*30)
= 500*(600+400+600)
=500*1600
=800000cm sq.
=80 m sq
= 500*(600+400+600)
=500*1600
=800000cm sq.
=80 m sq
but question that
how much of cardboard will have to be used for same ?
Area for one box =2×(30×20+20×20+20×30)=2×(600+400+600)=2×1600=3200
For 250 boxes we multiply 250 to surface area of one box
So 250 ×3200=800000 cm sq.
Ok??
Mark as brainliest pls
ya i understand
thanx

area of one box = 2 (30*20+20*20+20*30)=3200cm^2
so, area of 250 boxes =800000cm^2
hence cardboard used 800000cm^2
