🌟 Volume of Rectangular Prisms 🌟

Hi my amazing Grade 6 builders! 👋

Today we’re learning about Volume — the amount of space inside a 3D shape! We will focus on right rectangular prisms (like boxes, rooms, and cereal boxes). Volume tells us how much something can hold — water, toys, air, or even how big a swimming pool is!

1. What Does a Rectangular Prism Look Like?

Length
Width
Height

A right rectangular prism has 6 rectangular faces, like a box.

2. The Magic Formula

Volume = Length × Width × Height
V = l × w × h

Units are always cubic units: cm³, m³, etc.

3. Step-by-Step Examples

Example 1: A box is 5 cm long, 4 cm wide, and 3 cm high.
Volume = 5 × 4 × 3 = 60 cm³

Example 2: A room is 6 m long, 5 m wide, and 3 m high.
Volume = 6 × 5 × 3 = 90 m³

4. Let’s Practice Together! 🎉

Question 1

A cereal box is 25 cm long, 8 cm wide, and 30 cm high. What is its volume?

6000 cm³
(25 × 8 × 30) ⭐

Question 2

A swimming pool is 20 m long, 10 m wide, and 2 m deep. How much water can it hold?

400 m³
(20 × 10 × 2) ⭐

Question 3

A gift box has volume 480 cm³. It is 8 cm long and 6 cm wide. What is the height?

10 cm
(480 ÷ (8 × 6) = 10) ⭐

5. Volume in Real Canadian Life 🇨🇦

• How much water a fish tank or swimming pool holds
• How much space is in a moving box or shipping container
• How much soil you need for a garden
• How much air is in a classroom or hockey arena
• Packaging design for toys and food

You are now a Volume Expert! 🌟

Fantastic job! You can now calculate the volume of rectangular prisms.

Try measuring the length, width, and height of a shoebox at home and find its volume!

Love and proud high-fives,
