Hello my wonderful Grade 5 superstar! 👋
I'm Kashef and today we're learning how to Build Rectangular Prisms! A rectangular prism is a 3D box shape. We can build them using little unit cubes (1 cm × 1 cm × 1 cm). The number of cubes we use is the volume! Ready to be a 3D builder? Let’s go! 🚀
🧠 What is a Rectangular Prism?
It has 6 rectangular faces, 12 edges, and 8 corners.
Volume = Length × Width × Height (number of unit cubes)
🎯 Let’s Build and Calculate!
1. Build a prism that is 5 units long, 3 units wide, and 2 units high. What is the volume?
2. You build a box with 48 unit cubes. If length = 6 and width = 4, what is the height?
3. How many unit cubes to build a prism 4 cm × 5 cm × 6 cm?

You are a 3D Builder Expert! 🎉🥳
Kashef is super proud of you! You can now build rectangular prisms and find their volume.
Building with cubes helps us understand space — you're thinking like a real engineer and architect!
