What is the definition of a sphere?

Back

A sphere is a perfectly round 3D shape where every point on the surface is equidistant from the center.

What are the characteristics of a rectangular prism?

Back

A rectangular prism has six faces, all of which are rectangles, and opposite faces are equal in area.

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

What defines a cylinder?

Back

A cylinder is a 3D shape with two parallel circular bases connected by a curved surface.

Front

How do you calculate the volume of a sphere?

Back

The volume of a sphere is calculated using the formula V = (4/3)πr³, where r is the radius.

Front

What is the formula for the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated using the formula V = length × width × height.

Front

How do you find the surface area of a pyramid?

Back

The surface area of a pyramid is found by adding the area of the base to the area of the triangular faces.

Front

What is the formula for the volume of a cylinder?

Back

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

Front

What is the difference between a prism and a pyramid?

Back

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