A three dimensional shape is where you have height, width, and length where as in a two dimensional shape you only have height and length
a dodecahedron
A triangle is a shape with three sides and three angles. This is a very basic shape taught to young children.
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
Three-dimensional. It has height, width and depth.
No such shape exists.
a dodecahedron
In mathematics, they are usually refered to as Solids.
Any 2-dimensional shape can be folded to form a 3-d shape. For example, any work of origami.
Because they are dimesional figures either way!
It is a line.
It depends. Different objects require different formulas. For a basic cube, it is width times length times height
Two Dimensional means that there are two dimensions.
A globe is the most accurate representation of the Earth because it is a three-dimensional sphere that closely mirrors the actual shape of the planet. Flat maps distort the size and shape of landmasses when projecting a spherical surface onto a two-dimensional plane, resulting in inaccuracies in scale and distance.
like you can draw a three dimesional repesentation of a cube on a shhet of paper so we can "draw" a three dimesional representaion of the fourth dimension .It would be a cube inside a cube with all of the corners joined by a line from exteranl surface of the inner cube to the inner corner of the external cube. This in affect is a shadow of the fourth dimesion. See "Flatland" for explaination of how 2D would try to describe 3D..
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
Triangle is a shape with three sides.
