Classifying 3D Shapes

Front

What is a 3D shape?

Back

A 3D shape, or three-dimensional shape, is a geometric figure that has depth, width, and height, making it occupy space.

Front

What are the characteristics of a triangular prism?

Back

A triangular prism has two triangular bases and three rectangular faces, with the sides connecting the corresponding vertices of the triangles.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

How many faces does a cube have?

Back

A cube has 6 faces, all of which are squares.

Front

What is the difference between a cone and a cylinder?

Back

A cone has a circular base and tapers to a point (the apex), while a cylinder has two parallel circular bases connected by a curved surface.

Front

What is a square pyramid?

Back

A square pyramid is a three-dimensional shape with a square base and four triangular faces that meet at a single point (the apex).

Front

What is the formula for the volume of a cube?

Back

The volume of a cube is calculated using the formula V = s³, where s is the length of a side.

Front

What is the surface area of a cylinder?

Back

The surface area of a cylinder is calculated using the formula SA = 2πr(h + r), where r is the radius and h is the height.

Front

What is a face in geometry?

Back

A face is a flat surface on a three-dimensional shape.

Front

What is the difference between a solid and a hollow shape?

Back

A solid shape is filled with matter, while a hollow shape has an empty space inside.
