Step-by-step explanation:

LENGTH(l)=80 cm

BREADTH(b)=40 cm

HEIGHT(h)=20 cm

TSA OF CUBOID = 2(lb+bh+lh)

                             = 2[(80*40)+(40*20)+(20*80)] cm²

                             =2[3200+800+1600] cm²

                             =2[5600] cm²

                             =11200 cm²

LSA OF CUBOID=2(l+b)h

                            =2(80+40)20 cm²

                            =2(120)20 cm²

                            =40(120) cm²

                            =480 cm²
