3D Shapes

Front

What is a 3D shape?

Back

A three-dimensional shape is an object that has depth, width, and height, making it occupy space.

Front

Name the three types of 3D shapes based on their faces.

Back

The three types of 3D shapes based on their faces are polyhedra (with flat faces), curved shapes (like spheres and cones), and composite shapes (made of a combination of both).

Front

How many edges does a cube have?

Back

A cube has 12 edges.

Front

What is the difference between a face and an edge in a 3D shape?

Back

A face is a flat surface on a 3D shape, while an edge is the line segment where two faces meet.

Front

How many vertices does a cone have?

Back

A cone has 1 vertex.

Front

What is the formula for the volume of a cube?

Back

The volume of a cube is calculated using the formula V = a³, where 'a' is the length of one side.

Front

What is a vertex in the context of 3D shapes?

Back

A vertex is a point where two or more edges meet in a 3D shape.

Front

How many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

Front

What is the shape of the base of a cylinder?

Back

The base of a cylinder is a circle.

Front

What is the formula for the surface area of a sphere?

Back

The surface area of a sphere is calculated using the formula A = 4πr², where 'r' is the radius.
