You could build 43 or, if you have imagination, 85 of them. Which one is it?
901
3
I can do it with 130, in 2-dimensions. In 3-d fewer matchsticks will be required.
Find out the number of matchsticks that the learners would need to build 40 triangles
You would need to cut 4 matchsticks to create a perfect square.
6 squares of the same sizes are needed to build a 3 dimensional cube
Squares are actually also rectangles so you could make 8 rectangles without touching any of the squares. However, if you could cut the squares, that would be a different problem....
You can set how many matches there should be at the beginning of the game from 20 to 24.
A model?
40,8,20,25,35,30,14,9,19,17,22,32,
pyramid with 2 squares on top row, 3 squares on second row, 5 squares on third row, and 7 squars on bottom row
The answer depends on the size of the squares.
