Question

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. How many edges does the resulting solid have?

Answer 1

Total number of edges for resulting solid = 12

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 have to find the number of edges in the resulting solid after we cut the edges as told above.

There are two faces along the height which will become sharpened after we take out the cuts.

So the resulting shape would be like that of a cylinder with its both ends pointed.

So total number of edges = 4 + 4 + 4 = 12
