### Course: Geometry (all content)>Unit 8

Lesson 1: Volume of rectangular prisms

# Measuring volume with unit cubes

Explore the concept of volume, emphasizing that it's a measure of how much space something takes up. Practice the idea of measuring volume in cubic units, like cubic feet or cubic inches, by counting the number of unit cubes that fit into a 3D shape. Created by Sal Khan.

• If the radius of the base of right circular cylinder is halved. keeping the height same. what is the ratio of the volume of the reduced cylinder to that of the original.
• lol lol lol lol lololol lololol lol
• Okay!
:)
• are there any other videos on this?
:)
• Yes, there are many other videos on this
• How many cubes are in 1 layer
• Depends. If it a 6 by 6 by 6, it would be 36 in one layer
• I used to think volume is hard but all you have to do is multiply.
• Yes, I agree. It makes learning much easier than any other site.
• do you like blue
• Am I Blue?

Am I blue, am I blue
Ain't these tears in my eyes telling you
Am I blue, you'd be too
If each plan with your man done fell through

Was a time I was his only one
But now I'm the sad and lonely one, lonely
Was I happy till today
Now he's gone and we're through, am I blue

Was I happy till today
Now he's gone and we're through, am I blue
Oh he's gone, he left me, am I blue - Billie Holliday
• What is the name of the website you used? I would really like to use that too en practice measuring the volume with unit cubes.
