The side of the edge of the cube is 9. 9cm
<h3>How to determine the length</h3>
Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm
To find the edge of the face, we know that the face of the cube is a square
Formula for diagonal of a square = 
Where is the side of the square
We then have,

Make 'a' the subject
a = 
Simplify the surd
a =
× 
a = 
a = 
a = 9. 9cm
Therefore, the side of the edge of the cube is 9. 9cm
