The answer is: " 10,000 cm " .
_________________________________________________
Note: 100 cm = 1 m (exact measurement); in which:
"cm" = centimeter(s) ;
"m" = meter(s) ;
_________________________________________________
100 m = ? cm ?
100 m * (100 cm / 1 m) = __?__ cm ;
The units of "m" cancel out; and we have:
(100)* (100 cm) = 10,000 cm .
