The length of the line ed according to the description of the cube is; 8.5.
First, since the shape is a cube, it follows that the diagonal of the top face can be used to determine the length of the sides of the top face.
Therefore , we have; length of each side of the top face;
ag = ge = ef = fa = √288/2 = 6√2.
Also, the diagonal of a to d is; √432 = 12√3.
Hence, the length of ed in the group as evident from the length of sides of the cube's top face in which case,
Consequently, the length of line ed is;√432 × 8.5.
