Ellipses
Volume = π (3.142) x A x B x Depth (D)
Average Depth
Irregular Shapes
For irregular shapes, calculating the area is less accurate. You will need to
draw up the pool accurately to scale on graph paper using a square on the
paper to represent a metre (or foot) square of pool. When you have finished,
count the squares.
For partial squares, count anything over half as one and ignore any under
a half. When you have the area (A) multiply by depth (D) for the Volume in
cubic metres. If you have several depths, break up your area calculation for
each depth.
