What is a 3D shape?

Back

A 3D shape is a solid object that has three dimensions: length, width, and height.

Front

What are the characteristics of a cylinder?

Back

A cylinder has two parallel circular bases connected by a curved surface. It has a height and a radius.

Front

What defines a cube?

Back

A cube is a 3D shape with six equal square faces, twelve equal edges, and eight vertices.

Front

What is a cone?

Back

A cone is a 3D shape with a circular base that tapers smoothly from the base to a single point called the apex.

Front

What is a pyramid?

Back

A pyramid is a 3D shape with a polygonal base and triangular faces that converge at a single point called the apex.

Front

How do you calculate the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius and h is the height.

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

How do you find the volume of a cone?

Back

The volume of a cone is calculated using the formula V = (1/3)πr²h, where r is the radius of the base and h is the height.

Front

What is the formula for the volume of a pyramid?

Back

The volume of a pyramid is calculated using the formula V = (1/3)Bh, where B is the area of the base and h is the height.

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.
