How to use this tool

  1. Enter length, width, shallow depth, deep depth.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Volume = length × width × (shallow depth + deep depth)/2.

A WORKED EXAMPLE

Using length = 5 m, width = 4 m, shallow depth = 1 m, deep depth = 2 m, the result is 30 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

Which inputs does this calculation need?

Estimate water volume of a rectangular pool with a uniform depth slope. Enter length in m, width in m, shallow depth in m, deep depth in m. The filled example is editable and is not a saved personal record.

How should I interpret the result?

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
