hi please find the ans​

Answer 1

Answer:

4800cm²

Step-by-step explanation:

Given,

Length of cuboid = 80cm

Breadth of cuboid = 40cm

Height of cuboid = 20cm

Lateral Surface Area of cuboid = 2h(l+b)

                                                    = 2*20(80+40)

                                                    = 40(120)

                                                    = 4800cm²

Answer 2

Answer:

formulae =2h(l+b)

therefore, L=80cm,B=40m=4000cm,H=20cm

Now, 2x20 (4000+80)

=40x4080

=163200cm

=1632m
