3D shapes have edges, sides, and intersecting points
3d shapes with six faces are called hexahedra.
Many 3d shapes have a corner.
here are some: 2d shapes- square circle triangle Rectangle 3d shapes- cone cuboid cube prism
they are: ---sided pyramids and triangular prisms and 20 sided 3d shapes
Cylinder
They have length, width and depth
jam ur hype man
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.

Shapes can be categorized into two main types: two-dimensional (2D) and three-dimensional (3D). Common 2D shapes include circles, squares, triangles, and rectangles, each defined by specific properties like sides and angles. In 3D, shapes include cubes, spheres, cylinders, and pyramids, characterized by their volume and surface area. Each shape has unique mathematical properties and applications in various fields.
3d shapes with six faces are called hexahedra.
Cubes, pyramids, cones, and spheres are all 3D shapes.
3D shapes have three dimensions, namely length, breadth and height.
Polygons are 2d shapes whereas polyhedrons are 3d shapes
Give vidoes to understand the 2d and 3d shapes clearly
No because 2d shapes are plane such as polygons but example of 3d shapes are: pyramid, cone, cuboid, cylinder, sphere ... etc
2D shapes are flat and have only two dimensions—length and width—while 3D shapes include depth, adding a third dimension. This allows 3D shapes to occupy physical space, whereas 2D shapes are confined to a plane. Additionally, 3D shapes can have volume and surface area, whereas 2D shapes are characterized by perimeter and area. Examples include squares and circles for 2D shapes, and cubes and spheres for 3D shapes.
