3-D Shapes

Front

What is a 3-D shape?

Back

A 3-D shape, or three-dimensional shape, is a geometric figure that has depth, width, and height. Examples include cubes, spheres, and pyramids.

Front

Can you name some common 3-D shapes?

Back

Common 3-D shapes include cubes, spheres, cylinders, cones, and pyramids.

Front

What is the difference between a 2-D shape and a 3-D shape?

Back

A 2-D shape has only two dimensions (length and width), while a 3-D shape has three dimensions (length, width, and height).

Front

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

Back

A face is a flat surface on a 3-D shape. For example, a cube has six faces, all of which are squares.

Front

What is an edge in a 3-D shape?

Back

An edge is a line segment where two faces meet. For example, a cube has 12 edges.

Front

What is a vertex in a 3-D shape?

Back

A vertex is a point where three or more edges meet. For example, a cube has 8 vertices.

Front

What is the volume of a cube?

Back

The volume of a cube is calculated by raising the length of one side to the third power (V = side^3).

Front

How do you calculate the surface area of a cylinder?

Back

The surface area of a cylinder is calculated using the formula: Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is a net in relation to 3-D shapes?

Back

A net is a two-dimensional representation of a 3-D shape that can be folded to form the shape. For example, the net of a cube consists of six squares.

Front

What is a prism?

Back

A prism is a 3-D shape with two parallel, congruent bases connected by rectangular faces. Examples include triangular prisms and rectangular prisms.
