The T. S.A of a cuboid whose length, breadth and height are 20 cm, 10 cm and 40 cm respectively is

2800

Explanation:

length=20cm

breadth=10cm

height=40cm

Now,

T.S.A of cuboid=2(lb+bh+hl)

=2(20*10+10*40+40*20)

=2(200+400+800)

=2*14000

=2800

one way archaeology us understand the past is through the material objects it finds, allowing us to know what was being used, and when. for example a dig recently found a flute, believed to be the oldest musical instrument found to date.
