Lesson 4: Volume word problems# Volume: FAQ

Frequently asked questions about volume.

## What is volume?

Volume is the measure of how much space an object takes up. We often measure volume in cubic units, like cubic inches or cubic centimeters.

## What are unit cubes?

Unit cubes are cubes that measure exactly one unit on each side. We use them to help us calculate the volume of other shapes.

Try it yourself with these exercises:

## How do we find the volume of a rectangular prism?

There are a few different ways we can find the volume of a rectangular prism. We can use unit cubes to fill the prism and count how many we used, or we can multiply the area of the base by the height of the prism.

Try it yourself with these exercises:

## What does it mean to decompose a figure to find volume?

To decompose a figure means to break it down into smaller shapes. We can use this strategy to find the volume of more complicated shapes by breaking them down into shapes we know how to measure.

## How do we use volume in the real world?

Volume is used in a lot of different ways in the real world! For example, when we want to know how much liquid a container can hold, we're measuring its volume. When we're packing a moving truck, we need to know the volume of all the boxes we're putting in so we don't overfill it.

Comment: Sorry. If there's no other way to explain it easier. I'm all ears.(5 votes)- To find volume you would need to multiply Length x Width x Height. This means, say, we had a shape that was 12 meters high, 4 meters long, and 8 meters wide. You would multiply some easy numbers first, like 8 x 4, which equals to 32. Then, you would multiply 32 with 12, or 32 x 12, to get 384. Hopefully you understand how to solve for volume better now! Have a great day (:(4 votes)
