Venus and Mercury also have solid surfaces.
The solid figure that has 4 flat surfaces that are triangles is a tetrahedron. A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners. Each of the four faces of a tetrahedron is an equilateral triangle, making it a regular polyhedron.

the flat surfaces of a solid figure are the
Gas giants do not have solid surfaces like terrestrial planets do. Instead, their outer layers consist mainly of dense gases, such as hydrogen and helium. As you descend towards the core of a gas giant, the pressure and temperature increase immensely, but it does not transition to a solid surface.

A sphere.
A cylinder
it is when you for example==== surface area = 2(6)(4) + 2(6)(3) + 2(4)(3) = 108 in. square surface area of a solid is the sum of the areas of the outside surfaces of a solid
A SPHERE has no vertices and no FLAT surfaces
