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
A triangular base pyramid would fit the description.
sqaure base pyramid
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.
Any shape you like.
A pyramid.

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.

sqaure base pyramid
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!
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.

A 3D shape with one base and three faces can only have triangular faces.
