Gardeners maths question
« on: 06 April, 2009, 05:22:54 PM »
If a 1T bulk bag of soil will cover 10sq meters to a depth of 2 inches how deep will it fill an 8' by 4' raised bed?

An 8'x4' raised bed gives a suface area of 2.9728 square meters.

That's 29.7% of the 10 square meter bed.

The 10 square meter bed was covered to 2" (or 50.8cm), so 50.8 divided by 0.297 times 1 gives 17.1cm, or 6.73"
