1 m = 100 cm
3m + 5cm = 305 cm
1m + 40 cm = 140cm
305 cm - 140 cm = 165 cm
165 cm = 1.65m

The original length = 3 m + 5 cm
= 305 cm
( 1m = 100 cm)
Cut piece 1 m 40 cm = 140 cm
Balance = 305 - 140 cm
= 165 cm
= 1 m 65 cm

5 cm = .05 m
so the board is 3.05m long
40cm = .4m
so you cut off 1.4m
so the rest is easy
3.05m - 1.4m = 1.65 meters
fyi which would be 1 meter + 65cm

The piece you cut off is 1.4 meters. The remaining piece is 1.65 meters.
