Explanation:
To calculate the amount of wood needed to create a raised bed, you will need to know the dimensions of the bed.
Assuming the raised bed is rectangular, you will need to know the length and width of the bed, as well as the height of the bed.
Once you have these dimensions, you can calculate the surface area of the raised bed by multiplying the length and width of the bed together. This will give you the area of the bottom of the bed.
To calculate the total surface area of the bed, including the sides, you will need to multiply this area by 2 (since there are two sides) and add this to the area of the bottom.
So the formula for calculating the total surface area of the raised bed is:
Total surface area = (2 x length x height) + (2 x width x height) + (length x width)
Once you have this total surface area, you can then calculate how much wood you need by multiplying it by the thickness of the wood.
For example, if the total surface area of the bed is 100 square feet and you plan to use 2-inch-thick boards, you would need 200 cubic feet of wood.
It's worth noting that this calculation assumes that the raised bed has straight sides and right angles. If the bed has a more complex shape, the calculation will be more difficult.
