How to Calculate the Volume of a Net

Volume is the amount of space that is contained within a specified boundary: volume measurements account for three-dimensional space and can thus tell exactly how much space is contained in a net. The volumes of conically shaped nets can be computed by first measuring the radius and height and then applying each figure to the following equation: V = [(h)(π)(r²)]/3.

Instructions

- 1
  Measure the diameter of your net (make sure that you stay consistent in your measurements, whether they are in cm or in) by stretching a tape measure across the center of the net's opening. Measure the distance from rim to rim and then divide that number in half to find the net's radius, which you will use later in your calculations.
- 2
  Multiply pi (3.14159) by the radius squared -- this is the equation: (π)(r²). This will obtain the area of the base of the net. After you have found the area of the base, measure the height of the net (from its base to the tip) and then multiply the area of the base by the height.

  Divide the result of the previous step by 3 to obtain the total three-dimensional volume of the net.
