Is it possible to have a 3 sided 3D shape?

No such object exists with flat sides. three lines can only intersect in one point, coincide or be parallel so yes, no such object exists. There is an infinite number of 3 dimensional objects with 3 faces, just as there are an infinite number 2 dimensional objects with 2 sides.

Does a face on a 3D shape have to be flat?

Mathematically a face on a 3D shape is part of a plane and therefore is flat. We have had a discussion about explaining that a sphere has a curved surface; a cone has 1 face and 1 curved surface etc. However, the definition of an edge is that it is where 2 faces meet.

What 3 dimensional shape has no flat faces?

Ellipsoid
Ellipsoid (three-dimensional ellipse) is also considered as an answer to this question, as it also has no vertices or flat faces.

Is a 3 dimensional shape flat?

Teachers will often talk about the fact that 2D shapes are ‘flat’ and 3D shapes are not.

What 3d shape has 5faces?

Pentahedron

Name	Vertices	Faces
Square pyramid (Pyramid family)	5	5
Triangular prism (Prism family)	6	5

Can a face be curved?

A face is the part of the shape that has the largest surface area – some can be flat, some can be curved e.g. a cube has 6 flat faces whereas a cylinder has 2 flat faces and 1 curved face.

Can you have a curved face on a 3D shape?

Faces. A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one.

Which solid has no flat face?

sphere
A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices. Its face is in the shape of a circle.

How many faces cylinder have?

2
Cylinder/Number of faces

Why are flat surfaces called faces?

The flat surface that makes the front of this cube is called a face. Many solid figures have more than one face. An edge is the line segment where two faces meet. Many solid figures have more than one edge.

What do you call a 3D solid figures with flat surfaces?

The flat surfaces of three-dimensional figures are called faces. The faces meet at edges. The edges are line segments. The edges meet at vertices (plural of vertex).

How many faces does a 3D shape have?

A polygon-based 3D shape or polyhedron, has a minimum of….. yeah, 4 faces (Tetrahedron). If you remove one of the faces you would have an open figure with the three remaining faces extending indefinitely. You need that 4th face to cut the other 3 and close the volume.

Which 3D shape has no faces edges and vertices but only one curved surface?

A cylinder has two flat faces and one curved surface. So its curved surface area is the area of the curved part between the top and bottom faces which are circular in shape. Which 3D Shape has No Faces, Edges, and Vertices but Only One Curved Surface? A sphere is a 3D shape that has no faces, edges, and vertices. It has only one curved surface.

What are 3D shapes that have the same shape?

The two end faces of a prism are the same shapes, and the other faces are rectangles. A pyramid has a polygon as its base and the rest of its faces are triangles that meet at the same vertex. Here are the most common 3D shapes.

What is the simplest planar figure with only three faces?

The simplest planar figure is the triangle; since it has 3 sides, it is not possible to meet the said property with only 3 planar faces, hence there is no such 3 dimensional object.
