It has the lowest ratio of surface area to volume.
The correct answer is Sphere. All of these are geometric shapes, however only the sphere is a 3 dimensional one.
A triangle is one of the strongest shapes for construction. A square or rectangle can deform into a parallelogram when loaded with weight, but a triangle cannot change shape without breaking one of the sides.
not very, the triangle is one of the strongest supporting shapes.
A sphere, an ellipsoid, a toroid are some examples.
For earth there is only one moon and it has only one shape that is sphere...!
A point has no corners and no sides. There are several geometic shapes with no corners and only one side. Some of the shapes are circle, oval, and sphere.
For a simply connected convex polyhedron , that is, shapes that are topologically equivalent to a sphere, F - E + V = 2 where F = faces, E = edges and V = vertices. For shapes that are topologically equivalent to a sphere with one hole in it (torus or doughnut shape), F - E + V = 0 For shapes that are topologically equivalent to a sphere with two holes in it F - E + V = -2 For shapes that are topologically equivalent to a sphere with three holes in it F - E + V = -4 and so on.
All of those are 3-dimensional shapes.
It is a round 3d shape and it also has only one face. It is the shape of the earth
Most 3D shapes, such as a cube, cuboid etc. have more than one face (with the possible exception of a sphere).
There is not a name becasue there are many different shapes. A sphere, an ellipsoid, a torus (doughnut), toroidal shapes with two or more "holes", a paraboloid, semi-hyperboloid etc are all 3-dimensional shapes which have got just one curved surface.
A sphere, ellipsoid or toroid are examples of shapes with only one face. You cannot get fewer faces than that!
