    Cube Net
AI Thread Summary
To identify the net of a cube, one must recognize that it consists of six squares, corresponding to the cube's six faces. A useful method involves checking for configurations where one square has three adjacent squares or two squares each have two adjacent squares. This approach simplifies the identification process. The discussion emphasizes the importance of visualizing the arrangement of squares to successfully determine the net. Understanding these patterns can aid in effectively solving related problems.

To identify the net of a cube, you must observe 6 squares (since a cube has 6 sides).
Either one square should have 3 adjacent squares, or 2 squares should have 2 adjacent squares, or both.

Follow the same procedure to find the net of a cube. Like This :

hi phymat...

it's great, very educational..

thanks.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
