Identifying 3D Shapes

Front

What is a rectangular prism?

Back

A three-dimensional shape with six rectangular faces, where opposite faces are equal in area.

Front

What are the properties of a cylinder?

Back

A three-dimensional shape with two parallel circular bases connected by a curved surface, having a uniform distance from the center to the edge.

Front

Define a triangular prism.

Back

A three-dimensional shape with two triangular bases and three rectangular faces connecting the corresponding sides of the triangles.

Front

What is a sphere?

Back

A perfectly round three-dimensional shape where every point on the surface is equidistant from the center.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is the formula for the volume of a cylinder?

Back

Volume = π × radius² × height.

Front

Explain the surface area of a triangular prism.

Back

Surface area = (base area × 2) + (perimeter of base × height).

Front

What distinguishes a sphere from other 3D shapes?

Back

A sphere has no edges or vertices and is completely symmetrical.

Front

What is the relationship between the radius and diameter of a sphere?

Back

The diameter is twice the radius (Diameter = 2 × Radius).

Front

How can you identify a cylinder in real life?

Back

Common examples include cans, tubes, and pipes, which have circular bases and straight sides.
