### Course: Basic geometry and measurement>Unit 6

Lesson 1: Volume with unit cubes

# Volume intro

Finding volume, length, and area all involve measuring dimensions in order to quantify a certain aspect of an object or space. Although each property requires different calculations, they all rely on the same fundamental principle: taking measurements and using those measurements to derive a numerical value. When finding volume, you are measuring the amount of space that an object occupies. Created by Sal Khan.

• What is the difference between capacity and volume?
• Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. ... Volume is measured in cubic units, while capacity can be measured in almost every other unit, including liters, gallons, pounds, etc.
• How do you calculate the volume of an irregular shape?
• You can calculate the volume of an irregular shape - it just takes a few more steps:

First, break the irregular shape into smaller, regular shapes. (You should know how to calculate the volume of each of these smaller shapes.)

Next - one at a time - calculate the volume of each of the smaller shapes.

Finally, add up the volumes of all the smaller shapes. This gives you the total volume of the irregular shape.

Hope this helps!
• a 4-d is when a figure is 3-d holographic
• Human beings are literally incapable of seeing a 4D shape in its most true form. Consider:
If I had a sphere and we could only see in 2D, we'd just see a circle, not the whole sphere.
It's the same idea with 4D VS 3D.
• Hi everyone!💖
Hope y'all are all having a great day ✨

Just want to say, don't worry you're an AMAZING person, and I hope your life is going well ✨

And if you're having a bad day. Its okay, things will get better for you! 🥺❤
• You are a good person you make people happy
• what is volume
• In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet. Volume is also how loud a sound is. Look on your TV remote. There is a volume control button on it.

• Break the irregular shape into smaller shapes, then calculate the volumes of those. When you are done, add all the volumes together to find the total volume
