It has flat sides to balance on, a sphere just rolls around.
A sphere is likely to need more material for a critical mass compared to a cube. This is because a sphere has a lower surface area-to-volume ratio than a cube, meaning that for a given volume, a sphere encloses more mass within a smaller surface area. Therefore, to achieve critical mass, a sphere can often require less material than a cube of the same volume.
cone, cube, paper, cylinder, the hole than the sphere.
A cube has 8 vertices and 6 faces. Therefore a cube has 2 more vertices than faces.

Well, sweetie, a ball is a sphere because a sphere is defined as a perfectly round geometrical object in three-dimensional space. It's got the same distance from its center to all points on its surface, giving it that nice, smooth round shape. If a ball were a cube, it would roll all wonky and not be very good at being a ball now, would it?

Most 3D shapes, such as a cube, cuboid etc. have more than one face (with the possible exception of a sphere).
No. The surface to volume ratio of a sphere is always smaller than that of a cube. This is because the sphere has the smallest surface area compared to its volume, while the cube has the largest surface area compared to its volume.
surface area of sphere = 4πR2 volume of sphere = 4/3πR3 surface area of cube = 6s2 volume of cube = s3 since volumes are equal then s3 = 4/3πR3 s = [cube root (4/3π)] R surface area ofcube = 6 (cube root( 4/3π) times R)2 surface area sphere = 4πR2= 12.56 R2 surface area cube = 15.44 R2 So a sphere has less surface area than a cube with the same volume. Where R= radius of the sphere s=length of side of the cube Sorry,calculation above is now corrected - same equations, earlier made math error - cube has more surface area as you can see

A cube of platinum of the same size as a cube of silver will weigh more.
A large cube may have more mass than a small cube if it is made from a denser material or if it has a greater volume, meaning more matter is packed into the large cube. However, the size alone does not determine the mass.
The answer depends on what the substance is. A small solid cube will usually have more atoms than a larger cube filled with a gas.
