Question

Find the edge length of a cube if the surface area is 96cm^2?

Answer 1

The total surface area is 6 times the surface area of each face, that is:
\[A = 6 * l^2\]
Where A is the total surface area and l is the side length of the cube.
Now:
\[A = 6 * l^2 = 96 cm^2\]So rearranging the formula gives:
\[l = \sqrt{\frac{96}{6}}\]To give an answer of
\[l = \sqrt{16} = 4\]
