A cube is unique in that all of its faces are squares with side lengths, also known as edges, that have the same length (unlike rectangular prisms).Īlso make a note that the terms cube and rectangular cube both mean the exact same thing (some questions will refer to a cube as a rectangular cube). The most important word in this definition is equal. In math, what is a cube?ĭefinition: A cube is a box-shaped three-dimensional figure that has six equal and identical square faces. Now we are ready to learn how to find the surface area (sometimes referred to as SA) of a cube and we will start with a quick recap of some very important vocabulary and definitions. This guide also includes a completely free surface area of a cube calculator that can be used to make fast calculations and find the surface area of a cube almost immediately (and while we do not recommend relying on a calculator to solve surface area problems, having access to a calculator can be a very helpful tool when it comes to checking your work-but more on that later!) The Surface Area in terms of Surface Tension formula is defined as the measure of the total area that the surface of the object occupies and is represented as SA E / or Surface Area Surface energy / Surface Tension.The Surface energy is defined as the excess energy at the surface of a material compared to the bulk, or it is the work required to build an area of a particular surface. The following free How to Find the Surface Area of a Cube lesson guide is a step-by-step tutorial that will teach you how to use a simple method for calculating the surface area of a cube using the surface area of a cube formula to solve homework problems, test questions, and more. Fortunately, calculating the area of a cube is a pretty straightforward task as long as you are able to follow three simple steps for finding the surface area of any cube that are demonstrated in this lesson. Learning how to find the surface area of a cube and how to apply the surface area of a cube formula is a critical and important math/geometry skill that every student should master.
