Logarithms can be intimidating, but solving a logarithm is much easier once you realize that logarithms are just a different way to write exponential equations. Once the logarithms are rewritten in a more familiar form, you should be able to solve them as a standard exponential equation.

The "cubic" units of measure are three-dimensional units of measure and all refer to the volume of an object. Any measurement of a volume expressed in different units of measure can easily be converted to cubic feet. Calculating the volume of specific geometric shapes such as a rectangular prism or cylinder takes only a few simple steps.

Geometric mean allows you to find the mean value of a set of data, but instead of adding the values and dividing them as you would for the arithmetic mean, you need to multiply them before calculating the root. You can use the geometric mean to calculate the average return on an investment or to show how much a value has grown over a specific period.
