It has 4 faces
tetrahedron is a 4 faced 3d shape.
Area is usually pertaining to the area of a 2d object but surface is 3d object
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
d2 = a2 + b2 + c2 a, b, and c are dimensional distances which are perpendicular (like x, y, and z coordinate system) and d is the distance between 2 points separated by those dimensions (or a diagonal line between the 2 points).
There is no limit to the number of faces.
There are an infinite number of 3d shapes. For example you can have an infinite number of prisms with ends that are triangular, quadrilateral, or in the shape of any polygon.
The 3d shape that have five faces would be a triangular prism **************** or a pyramid
A 3d shape with 5 faces can be a square pyramid
3d shape Well actually it is a Cube
No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
A Pyramid is a 7 lettered 3D shape with triangular faces.
It cannot be a polyhedron nor any "normal" 3d shape.
a sphere
Sphere ( 0 faces , 0 edges , 0 vertices )
An icosahedron is a polyhedron has 20 faces, and is a 3D shape.
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
