Rectangle and Square Pools
Volume = Length (L) x Width (W) x Depth (D) or Average Depth
Circular
Volume = π (3.142) x Radius2 x Depth (D) OR Average Depth
Radius = Diameter divided by 2
Ellipses
Volume = π (3.142) x A x B x Depth (D) OR Average Depth
Irregular Shapes
For irregular shapes, calculating the area is less accurate. You will need to draw the pool accurately to
scale on graph paper using one square on the graph paper to represent a metre (or foot) square of pool.
When you have completed, 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.
