12 Sides.... A 3d Square is a cube!!
It has 6 sides and on the dice you can see that all the opposite sides equal 7. So this a good question but the 3D cube can be used in many ways such as jobs and math.
3D shapes have edges, sides, and intersecting points
A 3d shape with 10 sides is called a decahedron. I have added a link with some pictures of them. As you can see they look very different but all have 10 sides or faces.

About 26 sides, and 24 corners.
An arrow head has 4 sides and it is a quadrilateral polygon

In a virtual 3D environment a cylinder can have as many sides as it take for it to look convincing. Though for optimization purposes the fewer the better.
There are 14 faces.
