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

Back

A face is a flat surface on a 3D shape.

Front

How many faces does a triangular prism have?

Back

A triangular prism has five faces: two triangular bases and three rectangular faces.

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.

What is a cone?

Back

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

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.
