What is 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 a triangular prism?

Back

A triangular prism is a 3D solid with two triangular bases and three rectangular faces.

Front

What is a triangular pyramid?

Back

A triangular pyramid, or tetrahedron, is a 3D solid with a triangular base and three triangular faces that meet at a point.

Front

What is the formula for 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 and h is the height.

Front

What shape is the base of a rectangular prism?

Back

The base of a rectangular prism is a rectangle.

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a 3D solid that can be folded to form the solid.

Front

How do you find 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 difference between a prism and a pyramid?

Back

A prism has two parallel bases and rectangular faces, while a pyramid has one base and triangular faces that meet at a point.

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.
