Question

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

Answer 1

length=3.2m
breadth=30dm=3m
height=250cm=2.5m


surface area
=2(lb+bh+lh)
=2(3.2×3 + 2.5×3 + 3.2×2.5)
=2(25.1)

$50.2 {m}^{2}$
or

$502000 {cm}^{2}$

Answer 2

T. S. A=2(lb+bh+lh)
=2(3.2*3+3*2.5+2.5*3.2)
2*25.1=50.2sq m
