Find The Volume Of Cubes easy Math quiz
Teach kids to find volume of cubical shapes
When we talk about volume, we’re talking about the amount of space that something takes up. The volume of a shape tells us how much room there is inside the shape. One way to find the volume of a shape is to think about how many cubes it would take to fill up the shape.
For example, let’s say we have a cube that’s made up of little cubes. Each side of the big cube is made up of 10 smaller cubes. We can find the volume of the big cube by counting the number of smaller cubes it’s made up of.
To find the volume of the big cube, we need to know how many cubes it has in each of its three dimensions: length, width, and height. We can start by counting the number of cubes in the length.
The big cube has 10 cubes in the length, so we write “10” in the formula for finding the volume of a cube:
Volume = 10 x ? x ?
Next, we count the number of cubes in the width. The big cube also has 10 cubes in the width, so we write “10” in the formula:
Volume = 10 x 10 x ?
Finally, we count the number of cubes in the height. The big cube has 10 cubes in the height, too, so we write “10” in the formula:
Volume = 10 x 10 x 10
To find the volume of the big cube, we just need to multiply all three numbers together:
Volume = 10 x 10 x 10 Volume = 1000
So the volume of the big cube is 1000 cubic units.
We can use this same method to find the volume of other shapes made up of smaller cubes. Let’s say we have a rectangular prism that’s made up of smaller cubes. To find the volume of the rectangular prism, we just need to count the number of cubes in each of its three dimensions: length, width, and height.
Let’s say the rectangular prism has 20 cubes in the length, 15 cubes in the width, and 10 cubes in the height. To find the volume of the rectangular prism, we just need to multiply all three numbers together:
Volume = 20 x 15 x 10
Volume = 3000
So the volume of the rectangular prism is 3000 cubic units.
It’s easy to see how many smaller cubes a shape is made up of when the shape is made up of regular, even-sized cubes. But sometimes, the shape might be made up of cubes that are different sizes. In this case, we can still find the volume of the shape by counting the number of cubes it’s made up of and multiplying by the volume of a single cube.
For example, let’s say we have a pyramid made up of cubes. Some of the cubes are smaller than others, so we can’t just count the number of cubes to find the volume. But we can find the volume of the pyramid by counting the number of cubes it’s made up of and multiplying by the volume of a single cube.
Let’s say we have a pyramid made up of 100 small cubes and 50 large cubes. The small cubes have a volume of 0.5 cubic units, and the large cubes have a volume of 2 cubic units. To find the volume of the pyramid, we just need to add up the volume of all the small cubes and all the large cubes:
Volume of small cubes = 100 x 0.5
Volume of small cubes = 50
Volume of large cubes = 50 x 2
Volume of large cubes = 100
Total volume = 50 + 100
Total volume = 150
So the volume of the pyramid is 150 cubic units.
