Upon slicing each corner of a cube with a straight plane cut, how many total edges would be there in the remains? Visualize a cube. You know it has 6 faces, 8 corners, and 12 edges. Now, imagine a knife slicing away each corner with a straight plane cut. How many total edges are there now?



By cutting single corner of the cube 3 edges will be formed.
The cube has 8 corners.
hence cutting each corner will add 3*8=24 edges to the cube.
By default the cube has 12 edges.
Therefore,After cutting each corner of the cube there will be 12+24= 36 edges.
Answer is 36 edges.
