Well.. A sphere is a solid with only one surface. !
(Oh and the person who answered this before me didnt think about all the solids!)
Or if youre a surface with only one distinct sufaces/sides, or something that have no distinct inside and outside. Sphere have two distinct surfaces -- inside and outside, but they are, well, "joined" in a sense. What you will need is a Klein bottle. This object have only one side -- outside, inside whatever you want to call it, but there is only one surface.

The second person did not think of all the solids either! A solid sphere does have only one surface, as do ellipsoids, tori, paraboloids, etc. And those are just the less irregular ones.

A cone fits the description.
A Semi-Sphere :)
A face is a flat surface. The only solid with no flat surfaces is a sphere.
There is no solid that has those characteristics. To have an edge it must have another surface.

The "Surface Area" of the solid figure. Note, the word "total" in the answer above is not correct/needed - there can not be anything less than a surface area of a solid figure.

One if it is solid, two if it is hollow
