Question 366410
Can you please explain the process in finding the total surface area of a cube with an edge of 11ft?  (in laymans terms) 

...
we all know that cube has all sides/ edges equal.
Take a cube/box in your hand and number the faces of the cube.
you will have 6 faces numbered.
..
each face has an area with two edges of 11 ft each.
Area of 1 face = L*L = 11*11 = 121 sq.ft.
..
you have numbered 6 faces on your box/cube.
total area = 6 multiplied by area of 1 face.
..
6*121= 726 sq.ft is the total area.
..
To make a quick calculation you use the formula 
Total surface area of cube = 6*L^2
6*11*11= 726 sq. ft
