Step-by-step explanation:length L = 80 CM ;breadth, b = 60 cm and height, H =45 CM

Total surface area = 2(lb + bh + hl)

= 2 { (80 × 60) + (60× 45) + (45 × 80)} cm²

= 2(4800 + 2700 + 3600) cm²

= 2(11100)cm² = 22200cm² = 2.2m²

Step-by-step explanation:area of cuboid is 2(lb+bh+lh)

here l=80cm,b=60cm,h=45cm

therefore,

area of plastic used =2(80*60+60*45+45*80)

=2(4800+2700+3600)

=2(11100)

=22200cm^2
