The length of the 6h rod is# =265.2-230=35.2#

The mean length of 6 rods is #=44.2 cm#
The mean length of 5 rods is #=46 cm#

The total length of 6 rods is #=44.2xx 6=265.2# cm
The total length of 5 rods is #=46xx5=230 # cm

The length of the 6h rod is = [Total length of 6 rods] - [Total length of 5 rods]

The length of the 6h rod is# =265.2-230=35.2#
