Area = 2(lb + bh + hl)
= 2 ( 25×50 + 50×15 + 15×25)
=2( 1250+ 750 + 375)
= 2(2375)
= 4750 cm² or 0.475 m²
= 2 ( 25×50 + 50×15 + 15×25)
=2( 1250+ 750 + 375)
= 2(2375)
= 4750 cm² or 0.475 m²

We know that cardboard is coubodial shape
So.area of cardboard is 2(lb+bh+hl)
Therefore area is 2(25*50+50*15+15*25)
2(1250+750+375)
2(2375)
