develop the concept that the volume of rectangular prisms with whole-number edge lengths can be found by counting the total number of cubes that fill a shape without gaps. 

• Volume is the amount of space a 3D object takes up
• We measure volume in cubic units
• For rectangular prisms, we count the number of unit cubes that fill the shape
• No gaps or overlaps allowed!

​Volume

Tools We Use to Find Volume

• Unit cubes
• Rulers
• Grid paper
• Digital tools
• Physical models
Let's explore how these help us measure volume!

Finding the Volume of a Shape

To find the volume of a shape we take the length x width x height or L x W x H = V

1. Measure the length (L)

2. Measure the width (W)

3. Measure the height (H)

4. Multiply: L x W x H = V
   Remember: Volume is measured in cubic units (like cm3)

Step-By-Step for Finding Volume

​Length = 3 cm

​Width = 3 cm

​Height = 3 cm
