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
A 3D cone has two faces: one circular face at the base and one curved surface that wraps around the side. The base is flat, while the curved surface connects the base to the apex of the cone.
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
Any shape you like.

polyhedron
sqaure base pyramid
A triangular base pyramid would fit the description.
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!
You find the base of a figure depending on if it's 2D or 3D 2D- Get a measuring device and find the length of the base. 3D- Easiest way is to split it into parts. For example, you have a pentagon-shaped base, i would split it into 5 and find the base for 1 part and multiply it by 5.
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.
