prism
The 2 dimensions of 2d shapes and length and breadth.
They are 2 dimensional shapes that only have length and width.
Square.
You multiply length and breadth (width).
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
a prism
2d shapes only have length and width, while 3d shapes have length, width and depth.
Shapes with an irregular cross-section.
The 2 dimensions of 2d shapes and length and breadth.
You multiply the width with the length.
One similarity between prism and cylinder cross sections is that both shapes can produce polygons when cut by a plane. For instance, a cross section of a prism will reveal a polygon that corresponds to the shape of its bases, while a cylinder can also yield a circular cross section or, if cut at an angle, an elliptical shape. In both cases, the cross section remains consistent along the length of the shape, maintaining the same geometric properties throughout.
The difference is that two-dimensional shapes have a length and a width while three-dimensional shapes have a length, width, and depth. While some examples of two-dimensional shapes are circle, rectangle, and triangle, example of three-dimensional figures are a sphere, cuboid, and a pyramid.
3D shapes have three dimensions, namely length, breadth and height.
Shapes that have length, width and depth are considered to be 3 dimensional
Shapes are two dimensional; that is, they have length and height, like a square. Forms are three dimensional; they have length width and height, like a cube.
They are 2 dimensional shapes that only have length and width.
A 2 dimensional shape (or a 2D shape) is a shape withe a length and height, in some other cases, like a circle or oval or irregular shapes are also 2D shapes. Conclusion: A 2D shape is a shape that only have one section, that can be drawn.
