Cube volume calculator

Calculate cube volume by cubing its side length: V = s³. Enter the edge measurement and see the result, formula and example in cubic units.

Result

Three dimensions, six faces

Volume counts unit cubes inside; surface area counts squares on the boundary. Opening the net shows six faces without changing their measurements.

How do you calculate cube volume?

Use the edge length as three factors: s × s × s. Each face is a square with area equal to the edge squared; six faces make the total surface area.

V = s^{3}

s = V^{\frac{1}{3}}

How to use the calculator

Enter measurements with a decimal point or comma: results update immediately. Input units apply to every length; changing them converts the measurements. Changing result units leaves the shape unchanged. The control below the drawing reveals or hides its visual explanation. Copy results includes valid measurements and the result. Reset and Try this example restore the initial values and centimetre units.

Choose Edge to find volume, or Volume to find the edge using the cube root. Entered volume uses cubic input units; the inverse result is a length. Dragging the edge also updates the entered volume.

The first formula shows the relationship; the second substitutes measurements converted to the result unit. The ≈ sign indicates rounding, including in the substituted values.

A cube with a 4 cm edge

The cube contains 4 × 4 × 4 = 64 cubes of 1 cm³. Each face has area 16 cm², giving total surface area 96 cm².

From measurements to the result

Input: $s = 4 cm$
Result: $64 {cm}^{3}$

Calculation steps

Find the area of one square face.
$s^{2} = 4 \times 4 = 16$
Complete the calculation using the tool’s formula.
$V = 16 \times 4 = 64$

Units and interpretation

Volume uses cubic units: 1 m³ = 1,000,000 cm³ = 1,000 L. Capacity in litres is geometric; use internal measurements for real containers.

This formula requires six equal square faces. For three different edge lengths use cuboid volume.

Precision and numerical limits

Lengths range from 0 to 10¹² in the selected unit; triangle sides must be strictly positive. Results use two decimal places, with scientific notation for very small or large values. Calculations use browser precision: unrepresentable positive values produce an error. A rejected unit change keeps the previous data. Calculation takes place in your browser.

Entered volume may reach 10³⁶, provided the derived edge is at most 10¹² in the input unit. A rejected mode change keeps the previous data.
