Volume of Rectangular Prisms
Ever wonder how much water a fish tank holds or how much space is inside a shoebox? That's where volume comes in! The volume of a rectangular prism tells us the total space inside it.
The formula for finding volume is V = Bh, where V stands for volume, B represents the area of the base, and h is the height of the prism. For rectangular prisms specifically, since the base is a rectangle, we can expand this to V = lwh (length × width × height).
When calculating volume, you can multiply the dimensions in any order - the result stays the same. Just remember that your final answer will always be in cubic units (cm³, in³, ft³, etc.) because you're measuring three-dimensional space.
Quick Tip: Think of volume as counting how many small cubes would fit inside your rectangular prism. If each dimension is 1 unit, then each small cube is 1 cubic unit.
Let's look at an example: For a rectangular prism with length = 7 cm, width = 5 cm, and height = 3 cm, we calculate:
- V = l × w × h
- V = 7 × 5 × 3
- V = 105 cm³
This means our rectangular prism has a volume of 105 cubic centimeters.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
