Answer:

The purpose of contour lines is to represent the tridimensional shape of the terrestrial surface on a bidimensional map. Contour lines are the intersection of an horizontal plane parallel to the reference level and the topographical surface to describe. Consequently: Contour lines are always closed curves.

Answer:

Find the lateral surface area and total surface area of a cuboid of length 80 cm, breadth 40 cm and height 20 cm.

ANSWER

l=80cm,b=40cm,h=20cm

Therefore,

TSA = 2(lb+bh+hl)

=2(80×40+40×20+80×20)=11200 cm2

LSA = 2(l+b)h=2(80+40)20=4800 cm²

I hope this will be help you.
