Have you ever wondered how much space a toy or a block takes up? This space is called volume. Volume is the amount of space that a three-dimensional object occupies. We can measure volume using something called cubic units, which are like little cubes that fit together perfectly without any gaps or overlaps.
Let’s imagine we are building a small toy giraffe using cubes. If it takes 12 cubes to make the giraffe, then the volume of the giraffe is 12 cubic units. This means the giraffe takes up the space of 12 cubes.
Now, let’s look at a rectangular prism, which is like a box. If we count the cubes that make up this prism, we find there are also 12 cubes. So, the volume of the prism is 12 cubic units, just like the giraffe!
Isn’t it cool that even though the giraffe and the prism look different, they have the same volume? This shows us that different shapes can take up the same amount of space.
Let’s explore a bigger cube. This cube has three layers of cubes stacked on top of each other. Each layer has 9 cubes. If we add up all the cubes in the three layers, we get 27 cubes in total. So, the volume of this large cube is 27 cubic units.
What if we change the shape of this large cube into a big giraffe? As long as we use the same 27 cubes, the volume will stay the same, even if the shape changes!
Now it’s your turn! Try building your own animals or shapes using cubes. Count how many cubes you use to find out the volume in cubic units. Have fun creating and measuring!
Build and Compare: Gather some building blocks or small cubes. Try to build two different shapes, like a small house and a car. Count how many cubes you used for each shape. Are the volumes the same or different? Discuss why different shapes might have the same or different volumes.
Volume Hunt: Go on a volume hunt around your home or classroom. Look for objects that are made up of smaller parts, like a stack of books or a box of toys. Estimate how many cubic units each object might have. Then, try to measure or count to see if your guess was close. Share your findings with a friend or family member.
Shape Transformation: Use modeling clay or playdough to create a simple shape, like a cube. Count how many small cubes you could fit into your shape if it were hollow. Now, reshape your clay into a different form, like a pyramid or an animal. Even though the shape is different, discuss how the volume remains the same because you used the same amount of clay.

Three-dimensional objects take up space, which means they have volume. How do we measure volume, or the amount of space an object occupies? One way to measure volume is to use cubes or cubic units. Like other measurements, units have to be the same, with no gaps or overlaps. Connecting cubes fit perfectly together without any gaps or overlaps.
Let’s build a small object and measure its volume. It took twelve cubes to build this giraffe, which means the volume of this giraffe is twelve cubic units.
What is the volume of this rectangular prism? We can count the cubes: 8, 12. This prism has a volume of twelve cubes or cubic units.
Wait a second! The volume of this giraffe and the volume of this prism are both twelve cubic units. That’s interesting—projects that are different shapes can have the same volume.
Now, let’s measure the volume of this large cube. Notice that it has three layers of connecting cubes. The top layer has three, six, nine cubes. The three layers fit exactly on top of each other, which means they have the same number of cubes. Nine cubes in each layer means that there are 27 cubes in total. The volume of this large cube is twenty-seven cubic units.
Do you think the volume changes if we change the shape of this cube into, say, a big giraffe? We would still have the same number of connecting cubes, so the volume will remain the same.
