vCalc.Cube - Surface Area

The Surface Area of a Cube calculator computes the surface area of the cube based on the equation A = 6•s2, where s is the uniform length of the sides. CubeSurfaceArea-illustration.png         Cube - All sides
       of equal length (s) 

INSTRUCTIONS: Choose units and enter the following:

  • (s)  This is the length of one side of the cube.

Surface Area of a Cube (A):  The area is returned in square meters.  However, this can be automatically converted to other area units via the pull-down menu.

The Math / Science

Face of one side of a cube is a square of dimensions s by s.  The area of a square is:

  • A = s x s = s²

There are six equal sides of a cube, so the formula of the surface area of a cube is:

      SA = 6•s²
