We know that when find the perimeter of something that the units are just centimeters, inches, ect, and when we find the area of something that the units are squared, but what about finding the volume of something. What are the units for this? When finding volume the units are cubed. These can be very hard to remeber, however one way that I remeber is that anything that can be measured with a single string is going to just be units. Painting is how I think of area or surface area, these units are squared. Then for volume I think of 3D figures and know that the units are cubed.
