Calculating volume

[stoneburner]

My quick estimate for calculating approximate volume.

Basic calculation for volume

My “quick estimate” for volume is to assume the board planshape is an ellipse.  Estimated volume would be surface area of the ellipse (0.5 width x 0.5 length x 3.1416) times average thickness.

Basic calculation for volume

Assuming an average thickness of 1.9" for a 23" x 6’10" ellipse, the “rough” volume estimate would be 46 liters.
