If you have a perfect square that is equal to 1 acre, what is the length of the sides and how do you do it? One acre is 43,560 square feet so a square, with area one acre would have a side if length the square root of 43,560 or approximately 208.71 feet. That is. 208.71feet 208.71feet = 43559.86 square feet. Penny.
A triangular pyramid has a 4 vertices. There are 4 vertices on a triangular pyramid.. A triangular pyramid is a pyramid made up of 4 triangles. The vertices are the points where the edges of the triangles meet. They are sometimes called corner points. There are 4 faces, therefore, there are 4 vertices. There are 6 edges, and if they are all equal in length, it would be called a tetrahedron. Source(s): http://wiki.answers.com/Q/How_many_verti...
A square pyramid has a square base. It means, it has. 5 faces. 1 square face that is the bottom and 4 isosceles triangles above. 5 vertices, 4 at the base and 1 above. The 4 vertices at the base have 3 edges meeting together while the 1 above has 4 edges meeting together. 8 edges, 4 at the base and 4 above. 2 diagonals at the base.
