Soil- 'The real meaning of life'

There is NO soil on Mars or Venus!
WHY?

Soil Structure Recipie:

1. take some... Bedrock mmm Lava mmmm
2. weather for 10, 000 years using- wind, rain, glaciers
3. Add some Chemical weathering
4. AND some Biological- bacteria, fungi

Result: SOIL

Calculating purchase of soil.
Area = Length * Breadth
*result in sq metres
Volume = Length * Breadth * Height
* result in cubic metres

1 * Plot/s @ 4m * 4m *20cm
Volume = 4 * 4 * .2 *don't forget to convert cm to m
= 3.2 m3
6 * Plot/s
= 6 * 3.2m3
= 19.2 m3

#Homework- research the cost of:
1. various grades of soil
2. cost per cubic m (m3)
3. transport costs
