An icosahedron is a shape with 20 triangular faces - not more nor fewer. It can, therefore, have only 20 tall isosceles triangular faces.
An icosahedron is a shape with 20 triangular faces - not more nor fewer. It can, therefore, have only 20 short isosceles triangular faces.
According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.

A great deal of money and support was needed.
If you mean the regular polyhedra, they are: tetrahedron, cube (or hexahedron), octahedron, dodecahedron, icosahedron, (Plato's 50) plus: small stellated dodecahedron, great stellated dodecahedron, great dodecahedron, great icosahedron for 9. Maybe a sphere is a perfect curved 3D figure.
it was easier to move it then build it back up when needed
Eplans website is a great resource to help you with plans to build a deck on the ground. The website will also calculate the materials needed to build the deck.
YouTube and About has great tutorial videos on how to build a rabbit proof fence. Home Depot also has information and tools needed to build this project.
Besides agriculture, you can imagine that Great Britain were into ship building and they needed energy so they had coal mining efforts and they also needed iron (iron ore extraction) to build tools and hardware.
