square:plane::cube:
square - cube as circle - sphere
The completion of that analogy is 3-dimensional.
Oval
A triangular prism
Square is to cube as circle is to sphere....two dimensial compared to three dimensial figures.
If this is an analogy, the answer would be sphere.
If square is to plane, then cube is to space. A square is a two-dimensional shape that lies on a plane, which is a flat surface with only length and width. A cube, on the other hand, is a three-dimensional shape that exists in space, which includes length, width, and height. Therefore, the relationship between a square and a plane is analogous to the relationship between a cube and space.
Three-dimensional space

its 3-D
There are three plane figures and cube, which is three dimensional.
The analogy for "square: triangle" is "cube: tetrahedron." Just as a square is a two-dimensional shape with four equal sides, a triangle is a three-dimensional shape with three vertices. Similarly, a cube is a three-dimensional shape with six equal square faces, while a tetrahedron is a three-dimensional shape with four triangular faces. Both pairs represent geometric shapes with increasing dimensions and different characteristics.
