Question

Write a note on solid shapes in math.

Answer 1

Note on solid shapes :

The three-dimensional objects having depth, width and height are called solid shapes. Three-dimensional shapes have many attributes, such as vertices, faces, and edges.

• The flat surfaces of the $3D$ shapes are called faces.
• The line segment where two faces meet is called an edge.
• A vertex is a point where three edges meet.

Types of solid shapes are:

Cube		A cube is a solid or three-dimensional shape that has 6 square faces. The cube has All edges are equal $8$ vertices $12$ edges $6$ faces
Cuboid		A cuboid also called a rectangular prism, where the faces of the cuboid are a rectangle in shape. All the angle measures 90 degrees. The cuboid has $8$ vertices $12$ edges $6$ faces
Prism		A prism is a 3D shape that consists of two equal ends, flat surfaces or faces, and also have an identical cross-section across its length. A prism has $6$ vertices $9$ edges $5$ faces $–2$ triangles and $3$ rectangles
Pyramid		A pyramid a solid shape, whose outer faces are triangular and meet to a single point on the top. The pyramid is the square pyramid, i.e., it has a square base and four triangular faces. A square pyramid has, $5$ vertices $8$ edges $5$ faces
Cylinder		A cylinder is defined as a three-dimensional geometrical figure which has two circular bases connected by a curved surface. A cylinder has No vertex $2$ edges $2$ flat faces – circles $1$ curved face
Cone		A cone is a three-dimensional object or solid, which has a circular base and has a single vertex. A cone has $1$ vertex $1$ edge $1$ flat face – circle $1$ curved face
Sphere		A sphere is a three-dimensional solid figure which is perfectly round in shapes and every point on its surface is equidistant from the point is called the centre. The fixed distance from the centre of the sphere is called a radius, $r$ of the sphere. A sphere has No vertex No edges $1$ curved face
