Question

find the surface area of cuboid whose length=3.2m,breadth=30dm,height=250cmFind the surface area of a cuboid :

Answer 1

Surface area of a cuboid=2(lb+bh+hl)
Surface area=2((3.2m)(300m)+(300m)(2.5m)+(2.5m)(3.2m))
=2(960m²+750m²+8m²)
=2(1718m²)
=3436m²
Hope you are satisfied with the answer!

Answer 2

length = 3.2 m =3.2* 100=320cm
breadth = 30dm = 30*10=300cm
height = 250cm
surface area = 2(lb + bh + hl)
= 2( 320*300+300*250+250*320)
= 2(96000+75000+80000)
=2(251000)
=502000cm2
change into m2
1cm2=1/10000m2
502000/10000
=50.2m2
