All you do is count the surfaces of it. It's not like your trying to find an actual face.
:) If you count the surfaces you are sure to succeed.
a geometric figure having a specified kind or number of faces.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
A solid with four faces for maths is a tetrahedron.
A three dimensional object consisting of six identical square faces along three orthogonal planes.
A cube has 6 faces. The number of faces, alone, is not sufficient to figure out the number of edges. For example, a cube has 12 edges. A pentagonal pyramid also has 6 faces, but it has 10 edges.
The surface area of a space figure is the total area of all the faces of the figure
i don't know so figure it out yourself.
TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
Add the areas of all shapes or all faces that make up the composite figure.
'Enneahedron' - a solid figure with nine faces
A __________ is a space figure in which all faces are polygons.
A heptagon is a space figure with 7 faces
