Question 5
What is this 3D object called?
- rectangular prism
- pyramid
- sphere
- cone
pyramid
Hint: A pyramid has triangle faces that meet at a point on top.
Question 6
How many vertices (corners) does a rectangular prism have?
- 8
- 6
- 9
- 12
8
Hint: A vertex is a corner. There are 4 on the top and 4 on the bottom: 8.
Question 7
Ana builds a 3D object out of paper using 2 circles and a rectangle rolled into a tube. What did Ana build?
- rectangular prism
- cone
- cylinder
- pyramid
cylinder
Hint: Think about which object has those faces. A cylinder has 2 flat circle faces and a curved side, like a can.
Question 8
How many flat faces does a cylinder have?
answer box
2
Hint: One circle on the top and one on the bottom. The side is curved, so it isn't a flat face.
Question 9
