a). 1 m = 100 cms , 1 feet = 30.48 cms, 1 inch = 2.54 cms. So cms is the smaller unit relatively. Hence, the number associated would be also largest. So, if we want the largest number, we should express it in cms. b). 1 feet = 30.48 cms. So, 6 feet = $30.48 \times 6 \,cms$ = 182.88 cms = 183 cms (rounded off).
