Hello my wonderful Grade 5 superstar! π
I'm Kashef and today we're learning how to Count Cubic Units! Cubic units are little cubes (like 1 cm Γ 1 cm Γ 1 cm) that fill up a 3D shape. The total number of these cubes is the **volume**! Ready to count and build? Letβs go! π
π§ What are Cubic Units?
Each small cube is 1 cubic unit (1 cmΒ³).
Volume = How many cubic units fit inside without gaps.
This layer has 6 cubic units
βοΈ Counting Examples
Example 1: A box that is 3 units long, 2 units wide, and 4 units high.
Volume = 3 Γ 2 Γ 4 = 24 cubic units
Example 2: A flat layer 5 Γ 3 = 15 cubic units. If there are 2 layers, total = 30 cubic units
π― Letβs Count Cubic Units!
1. A rectangular prism is 4 units long, 3 units wide, and 2 units high. How many cubic units?
2. This shape has 3 layers. Each layer has 12 cubes. What is the volume?
3. A cube has sides of 5 units. How many cubic units?

π How many blocks fit in a toy box
π§ͺ Quick Cubic Units Quiz
Question: A box is 6 units long, 4 units wide, and 3 units high. How many cubic units?
You are a Cubic Unit Counter Champion! ππ₯³
Kashef is super proud of you! You can now count cubic units to find volume.
This is how we understand how much space things really take up β you're thinking in 3D like a scientist!
