The volume of a space can be calculated by multiplying the height and area of that space. Calculating cubic feet for different units formulae From feet. Below is an example of how to calculate volume for a box built from ¾ thick material with dimensions of 16 by 34 by 14.
They are usually easy to measure due to the regularity of the shape.
Multiply the 3 measurements that you just converted into feet together. Lets say that the cost to purchase the material per cubic feet is 07 dollars. To calculate the port length of a round port enter the diameter of the port D the box volume Vb in cubic feet and the desired tuning frequency Fb. For example using the new measurements that we found in the previous step we would multiply 2 x 3 x 1 and get 6 as our answer.
