What is a 3D shape?

Back

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

Front

What are the properties of a pyramid?

Back

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

Front

How many faces does a cube have?

Back

A cube has 6 faces, all of which are squares.

Front

What distinguishes a rectangular prism from a cube?

Back

A rectangular prism has rectangular faces, while a cube has square 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 and h is the height.

Front

What is a cone?

Back

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

Front

What is the surface area formula for a cube?

Back

The surface area of a cube is calculated using the formula SA = 6a², where a is the length of a side.

Front

What is the difference between a sphere and a cylinder?

Back

A sphere is a perfectly round 3D shape with all points on its surface equidistant from its center, while a cylinder has two circular bases and a curved surface.

Front

How do you calculate the surface area of a rectangular prism?

Back

The surface area of a rectangular prism is calculated using the formula SA = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

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

Back

The diameter of a circle is twice the length of the radius (d = 2r).
