It depends on whether you are measuring the thickness of the board (5 mm) or length (5 dm).
It is 65 cm.
25 square meters
basically, no. its simple 5m x 5m = 25m2 so a room 30m2 wont work
-7m - 3m + 5m = -5m
5m = 40m = 40/5m = 8
It is equivalent to 2,500 square centimeters
50miles or 5m or 5cm
1 metre=100 centimetres so, .5m=100*.5cm .5m=50cm
It is 65 cm.
5m
25 square meters
It would contain 5*5*5 = 125 cubic meters
5m-5n+5m+5n When simplified: 10m
-7m - 3m + 5m = -5m
basically, no. its simple 5m x 5m = 25m2 so a room 30m2 wont work
5m = 40m = 40/5m = 8
5m 80mm
