Cubic Meter

What Is a Cubic Meter?  

A cubic meter is a standard unit used to measure volume. It is equal to 1000 liters (one thousand liters). The symbol for a cubic meter is m³ or meter cube. A cubic meter is formed when we make a cube whose length, width, and height are all 1 meter. Since all sides of a cube are equal, the volume is found by multiplying: Volume of cube = length × breadth × height.  

We will discuss cubic meter, how big it is, and how to calculate it using the cubic meter formula. You’ll also see how cubic meters are converted into other units like liters, cubic centimeters, cubic feet, and cubic yards.

How Big Is a Cubic Meter?  

A cubic meter (m³) is a unit of volume in the metric system that represents the space occupied by a cube with sides of 1 meter in length. Imagine a box that is 1 meter long, 1 meter wide, and 1 meter high. The space inside that box equals 1 cubic meter. One cubic meter is equal to 1,000 liters.

For example:  

• A shipping container is a big box used to carry goods.

  • A 20-foot container can hold about 33 m³ of space.

  • A 40-foot container can hold about 67 m³ of space.

  Since 1 m³ = 1000 liters, this means:

  • A 20-foot container ≈ 33,000 liters

  • A 40-foot container ≈ 67,000 liters

  In simple words, a 40-foot container is about twice as big as a 20-foot container.

 

Cubic Meter Formula  

The cubic meter formula calculates the volume of any three-dimensional object in cubic meters. For example, if the sides of a cube or the length, breadth, and height of a cuboid are measured in meters, then their volume will also be expressed in cubic meters (m³).

The basic formula is:  

Cubic Meter (m³) = Length (m) × Width (m) × Height (m)  

Example :
Find the volume of a box with Length = 2 meters, Width = 1.5 meters, and Height = 1 meter.

Formula:
Volume = Length × Width × Height

Solution:
Substitute the values:
Volume = 2 × 1.5 × 1

Multiply length and width:
2 × 1.5 = 3

Multiply with height:
3 × 1 = 3

Final Answer:
Volume = 3 m³

So, the box has a volume of 3 cubic meters.

The cubic meter formula is useful in construction and engineering to find the amount of material or space needed.  

 

Cubic Meter Conversions  

To use cubic meters effectively in real-life situations, it’s important to know how they convert to other common volume and area units.  

 

Cubic Meter to Cubic Centimeter  

Since one meter equals 100 centimeters, and a cubic measurement involves all three dimensions (length, width, and height), the conversion from cubic meter to cubic centimeter is:  

1 cubic meter = 100 cm × 100 cm × 100 cm = 1,000,000 cubic centimeters  

So, if you have 2 m³:  

2 cubic meters = 2 × 1,000,000 = 2,000,000 cubic centimeters  

The cubic meter to cubic centimeter conversion is often used in science labs and for smaller liquid measurements.  

 

Cubic Meter to Square Meter  

A square meter (m²) measures area, while a cubic meter (m³) measures volume. However, there’s a relationship when you know the height:  

Cubic Meter = Square Meter × Height  

To convert cubic meters to square meters, divide the volume by the height:  

Square Meter = Cubic Meter ÷ Height (in meters)  

Example:  

If a tank has a volume of 5 m³ and a height of 2.5 m:  

Area = 5 ÷ 2.5 = 2 square meters  

While direct conversion between cubic meters and square meters isn't possible without the height, you can calculate it with the height data.  

 

Cubic Meter to Meter  

Cubic meter is a volume, while meter is a length. However, for a perfect cube:  

Cubic Root of Volume = Length of one side  

To convert cubic meters to meters, take the cube root:  

1 cubic meter = ∛1 = 1 meter  

8 cubic meters = ∛8 = 2 meters (each side of the cube)  

This type of conversion is useful when finding the side length of a cube given the total volume.  

 

Cubic Meter to Cubic Feet  

1 cubic meter = 35.3147 cubic feet  

Example:  

3 cubic meters = 3 × 35.3147 = 105.9441 cubic feet  

This conversion is important in construction and interior design when switching between metric and imperial systems.  

 

Cubic Meter to Cubic Yards  

1 cubic meter = 1.30795 cubic yards  

Example:  

5 cubic meters = 5 × 1.30795 = 6.53975 cubic yards  

This cubic meter to cubic yards conversion is common in landscaping, cement mixing, and waste management.

Practical Examples Using Cubic Meter Conversions

Example 1:  We need to convert 2 cubic meters (m³) into cubic centimeters (cm³), cubic feet (ft³), and liters (L).

1. Conversion into cubic centimeters (cm³)

1 cubic meter = 1,000,000 cubic centimeters

Therefore,
2 m³ = 2 × 1,000,000
= 2,000,000 cm³

2. Conversion into cubic feet (ft³)

1 meter = 3.2808399 feet

Therefore,
1 cubic meter = 1 m × 1 m × 1 m
= 3.2808399 × 3.2808399 × 3.2808399
= 35.3147 cubic feet (approx)

Now, for 2 cubic meters:
2 m³ = 2 × 35.3147
= 70.6294 ft³

3. Conversion into liters (L)

1 cubic meter = 1000 liters

Therefore,
2 m³ = 2 × 1000
= 2000 liters
 

Final Answer:

• Capacity in cubic centimeters = 2,000,000 cm³
• Capacity in cubic feet = 70.6294 ft³
• Capacity in liters = 2000 L

 

Example 2:  We need to convert 4 cubic meters (m³) of soil into cubic yards (yd³).

Conversion into cubic yards (yd³)
1 cubic meter = 1.30795 cubic yards
Therefore,
4 m³ = 4 × 1.30795
= 5.2318 yd³

Final Answer:
Capacity in cubic yards = 5.2318 yd³

 

Example 3: We have a concrete slab with a volume of 3 cubic meters (m³) and thickness of 0.15 meters. We need to find the floor area.

Formula for area from volume:
Area = Volume ÷ Thickness

Substituting the values:
Area = 3 ÷ 0.15 = 20 m²

Final Answer:
Floor area = 20 m²

Step 3: Substitute values
Side = ∛27 = 3 meters

Answer: 3 meters

 

Example 4: Convert 5 cubic meters into cubic feet.

Solution:
Step 1: Conversion factor
1 meter = 3.2808399 feet
