What is a 3-D shape?

Back

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

Front

What are the characteristics of a pyramid?

Back

A pyramid has a polygonal base and triangular faces that converge at a single point called the apex.

Front

What is a rectangular prism?

Back

A rectangular prism is a 3-D shape with six rectangular faces, where opposite faces are equal in area.

Front

What defines a triangular prism?

Back

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

Front

What is a cone?

Back

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

Front

How do you calculate the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated by multiplying its length, width, and height (V = l × w × h).

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) × base area × height.

Front

What is the surface area of a cone?

Back

The surface area of a cone is calculated using the formula SA = πr(r + l), where r is the radius and l is the slant 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.

Front

What is a sphere?

Back

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