When I think about "square units," I automatically think about measuring a specific object or space. This makes us think about the area L x W of a specific item. Square units are precisely measuring the location of an object. It can be measured in feet, which I am most familiar with, but it can also be measured in inches or meters as well. When I think about "cubic units," my mind goes directly to a glass or ice cube because this term relates to volume, L x W x H. Cubic units are often measured in feet, centimeters, or meters. The floor in a room can be measured in square feet. A bookshelf can be measured in cubic meters or feet. The refrigerator can be measured in cubic units as well
