I have this problem that I can't figure out. I've had quite a few attempts, but am really not sure where I'm going wrong. It's a simple question, so I'm sure it's something silly I'm doing...
A flash flood left a 200 hectare property ankle deep (100 mm) in water. How much water is this in mega litres? (1 hectare = 100m x 100m. 1 litre = 1000 cm3)
So, if 1 hectare = 100m2, then 200 hectare = 20,000m2.
Based on this, to determine the volume of water, we could multiply the area by the height of the water - 100mm, or 0.1m. 20,000m2 * 0.1m = 2,000m3.
I now have to convert this to litres, and by knowing that 1L = 1cm3, I should convert m3 to cm3. 1 m3 = 1,000,000cm3, so 2,000m3 = 2,000,000,000cm3.
Now, if 1 L is equal to 1000cm3, then 20,000,000,000cm3 = 2,000,000L.
Then, if 1 Megalitre = 1,000,000 L, then 2,000,000L = 2 megalitres.
However, according to the quiz sheet, this is incorrect...Could someone please explain?
