Understanding 3D Figures and Surface Area

What defines the faces of a 3D figure?

• Only the bottom surface

• Any curved surface

• Only the top surface

• Any flat surface

How do you describe a net in relation to a 3D figure?

• A 3D representation

• A 2D representation that can be folded into a 3D figure

• A complex mathematical formula

• A type of 3D printing technique

How is the surface area of a 3D figure calculated?

• By calculating the composite area of the net

• By measuring the volume

• By measuring the height only

• By counting the number of faces

What makes a 3D figure a prism?

• Having two parallel base faces

• Having triangular sides

• Being able to roll

• Having one base

What is the primary difference between prisms and pyramids?

• Prisms have no bases, while pyramids have one

• Prisms have two parallel base faces, pyramids have one base

• Pyramids can only have triangular bases

• Prisms are always larger than pyramids

How do you find the area of a rectangle in a net?

• Length plus width

• Base times height

• Height divided by 2

• Base plus height

What is the base shape of a triangular pyramid in its net?

• Circle

• Triangle

• Rectangle

• Square

Which formula is used to find the area of a triangle in a net?

• Base times height

• Base times height divided by 2

• Length plus width divided by 2

• Base plus height

What identifies a figure as a rectangular pyramid?

• Having two rectangular bases

• Having a rectangular base and triangular sides

• Having all sides as rectangles

• Being able to unfold into a perfect square

In a triangular prism's net, what shapes make up the sides?

• Squares and rectangles

• Rectangles and triangles

• Triangles only

• Only rectangles
