Snow on the ground has a density roughly 30% that of water.

What area of field did we need to make a snowball
2m across?
Snow on the ground has a density roughly 30 that
of water.
The snow is 5cm deep
Snow made into a snowball is roughly 60 as dense
as water.
2
And this sphere must have a volume of 4/3pr3,
which is
Surface snow is only half as dense as snowball
snow, so wed need twice as much in volume.
About 4.2 cubic metres?
Did you bring a calculator?
3
So wed need 8.4m3 of surface snow?
At a depth of 0.05m, the area would have to be
167.552m2
Cant you just enjoy the snow for once instead of
doing maths the whole time?
You did not just do that in your head.
