Answer:
Number of edges in the resulting solid = 12
Step-by-step explanation:
A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.
We are supposed to find the number of edges that are in the resulting solid.
In some corners , if we take out inch from both, then there would be nothing remaining.
