Sometimes. Any face can be defined as a base of a prism; but pyramids may have one face that is a base and not a triangle.
To determine the base of a 3D figure, first identify the shape that the figure rests upon or the face that is considered the bottom in its natural position. For common shapes like prisms or cylinders, the base is typically a flat polygon or circle. In more complex figures, analyze the orientation and context to decide which face serves as the base for stability or support. Visualizing the figure or using physical models can help clarify which side should be considered the base.
only a 3D figure has a face so no
It means the base in a 3D figure. For example, if it was a pyramid. the bottom part would be the base and you get the area of that base
sqaure base pyramid
A triangular base pyramid would fit the description.
Any shape you like.

Since a face of a 3d figure is the same as a side, you have two faces sharing a face! The result is lots of coincident faces!
length times width i think* * * * *There are different formulae for calculating the surface areas of different 3D figures. If the 3D figure is a polyhedron, then each face is a ploygon and you can use the various formulae to calculate the area of each face and then add them together.There are straightforward equations for ellipsoids, and members of the conic family but other 3D shapes have more complicated formulae.
To find the base of a figure, you first need to identify the shape of the figure. The base of a figure is typically the bottom or lower side that forms the foundation or support for the rest of the shape. For example, in a triangle, the base is usually the side on which the triangle stands. In a rectangular prism, the base is one of the two parallel and congruent rectangular faces.
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.
