To measure 720mm with a 30cm ruler, first note that 720mm equals 72cm. Since the ruler only measures up to 30cm, you would need to use it multiple times. Measure 30cm twice to get 60cm, then measure an additional 12cm using the ruler, which can be achieved by marking the 12cm point on the ruler after measuring the full 30cm twice. This will give you a total of 72cm or 720mm.
720mm equals 72cm
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
First you change cm to inches. Then you multiply that by 12.
