How to Build a Cardboard Pyramid
Start with either two or four refrigerator boxes. Cut all boxes as shown.
You will need four equilateral triangle pieces (all sides the same length) that have tabs along two of the sides. If you only have two boxes, cut them like this:
h=height
B=base
1. Measure 1/2 B
2. Calculate
h = B x .866

If you have four boxes, cut them like this for a taller pyramid:
h=height
B=base
1. Measure H
2. Calculate
B = h / .866
You should now have four equilateral triangle panels that look like this:
Lay them all flat and attach all seams as such (with the exception of the last seam):
You should now be able to stand your pyramid up and attach the last seam together and cut a door way.
