Height =170 cm It should be given in SI unit i.e., in metre =170 cm=1.70 m (Also, decimal after one digit) In scientific method it is written as 1.70× 102 cm

Q. The height of a man is measured by a metre scale having graduations $m$ centimetre only and the height turns out to be $170 c m$ . The scientific method for reporting the measurement is

$170 \times 1 0^{0} c m$

$1.700 m$

$170 c m$

$1.70 \times 1 0^{2} c m$

Height $= 170 c m$ It should be given in $S I$ unit
i.e., in metre $= 170 c m = 1.70 m$
(Also, decimal after one digit)
In scientific method it is written as
$1.70 \times 1 0^{2} c m$
