These notes cover the methods available for the determination of the volumes of three dimensional figures and earthworks. Generally the methods are based on using field survey techniques to acquire data that represents the shape of the land so that volume calculations can proceed.

The methods are as follows:

• Rectangular Base Method
• Triangular Base Method
• Balance of Cut and Fill
