3D Geometry shapes

Front

What is a 3D shape?

Back

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

Front

Define a sphere.

Back

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

Front

What is a cylinder?

Back

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

Front

What is a pyramid?

Back

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

Front

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

How do you find the surface area of a sphere?

Back

The surface area of a sphere is calculated using the formula A = 4πr², where r is the radius.

Front

What is a cone?

Back

A cone is a 3D shape with a circular base and a single vertex, tapering smoothly from the base to the apex.

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 converge at a point.

Front

How many edges does a cube have?

Back

A cube has 12 edges.

Front

What is the height of a cylinder if the volume is 226.08 m³ and the base radius is 3 m?

Back

The height of the cylinder is 8 m.
