![]() ![]() Two-dimensional shapes do not have any third axis, just the x and y-axis. For example, a circle is a 2-D shape while a sphere is a 3-D shape.ģ-D shapes have three coordinates on the axis, usually labelled as x,y and z. What is the difference between 2D and 3D shapes?Ģ-D Shapes are two-dimensional (length and width), whereas 3-D shapes are three-dimensional (length and width and height). More examples of this are balls, planets, suns and stars just to name a few. Other examples include a cone which you may find on the street, pyramid-rooftop buildings and cylinders which you could find in both industrial and agricultural industries.įinally, another shape you are probably familiar with is the sphere-another 3-D shape that you can find easily in your local supermarket or park. You might also add ice-cubes to your drinks in summer. One shape that you might use every day is a box or cuboid, which can be very useful if you want to take things with you in your car or on the bus. Many of these come from nature, while many others are designed by humans for specific uses. Most 3-D shapes are found in the world around us. The polyhedron has five faces, five corners and eight edges. ![]() The tetrahedron (also known as the triangular-based pyramid) has four faces, four corners and eight edges. The square-based pyramid (or pyramid) has five faces, five corners and eight edges. The two ends of the cylinder can be circular or oval.Ī triangular prism has five faces, nine edges and six corners.Ī pentagonal prism has seven faces, fifteen edges and ten corners.Ī hexagonal prism has eight faces, eighteen edges and twelve corners. The cylinder has one curved area, two faces and two edges. The pointed tip of the cone is known as the apex. The cone has a curved surface, a flat base, one edge and one corner. A cuboid is also known as a rectangular prism. All the sides of the cube are equal in length.Ī cuboid also has six faces, twelve edges and eight corners. The hemisphere has one curved surface, one flat face, and an edge.Ī cube has six faces, twelve edges and eight corners. Height, also called depth, which is how much space it takes up in the vertical direction (from the bottom of something to the top of something). Width, also called breath, which is a measure of the distance on the shorter side of an object (how wide something is). Length, which is a measure of the distance on the longer side of an object (how long something is). ![]() Some properties that 3D shapes have in common: They Have Three Dimensions Interested in helping your children succeed academically? Get started here. A 3-D shape is a geometric figure which has height, width and depth.Įxamples of 3-D shapes in the world around us include a piece of paper, a desk or a bookcase. What is a 3-D Shape?ģ-D is short for three-dimensional. Whether you have a child in Primary school or just want to brush up your knowledge of different shape names, here is a useful guide to answer the basic questions about 3-D shapes. Other more complex shapes include pyramids, cones, spheres and cylinders, among others. The most common 3D shape example is the cube, which we will learn more about in a moment. They can be created from two-dimensional shapes by rotating them in three dimensions. It is a win-win for us both! For more info, see the Disclosure Policy.ģ-D shapes are a part of geometry.
