HW: 3D Cross sections and Nets

Front

What is a net in geometry?

Back

A net is a two-dimensional shape that can be folded to form a three-dimensional figure.

Back

Triangular Pyramid

Front

What is a cross-section?

Back

A cross-section is the intersection of a solid and a plane, showing a two-dimensional shape.

Front

What shape will the vertical cross-section of a cube be?

Back

Square

Front

What shape will the horizontal cross-section of a sphere be?

Back

Circle

Front

What is the shape of the cross-section of a cone?

Back

Triangle

Front

What is the difference between a pyramid and a prism?

Back

A pyramid has a polygonal base and triangular faces that meet at a point, while a prism has two parallel bases and rectangular faces.

Front

What is the formula for the surface area of a cube?

Back

Surface Area = 6a², where 'a' is the length of a side.

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where 'r' is the radius and 'h' is the height.

Front

What shape does a net with one circular base and a curved surface create?

Back
