Answer:
False
Step-by-step explanation:
The fact that the figure is a solid means that there are more than two dimensions involved. However, even if the solid has three dimensions, there are certain figures that can be described without giving out all the three dimensions.
An example would be a cylinder with a circular cross-section. This solid can be described by simply expressing the diameter (or radius to the cross section) and its length.
In fact, a cube can simply be expressed by giving only one dimension since the length of the side of the cube is constant throughout.
Anyway, since your post premises on "To describe a geometric solid it suffices to have two dimensions" then the answer is FALSE (simply because it is not always true).
