cbrt
Learn how to use the cbrt function in Notion formulas.
The cbrt() function returns the cube root of its argument. cbrt() accepts only numbers.
1
cbrt(number)
The argument is
aa
where:
a3\sqrt[3]{a}

1
cbrt(8) // Output: 2
2
3
cbrt(64) // Output: 4
4
5
// Total surface area of cube with Volume 300m³
6
// using formula 6a², where a = edge length
7
6 * cbrt(300)^2 // Output: 268.88428479343
8

The example database below calculates several properties of a cube given a specific volume.

// Side Length
format(round(cbrt(prop("Volume (m³)")) * 100) / 100) + "m"
// Side Area
format(round(100 * cbrt(prop("Volume (m³)")) ^ 2) / 100) + "m²"
// LSA (Lateral Surface Area - 4 sides)
format(round(4 * cbrt(prop("Volume (m³)")) ^ 2 * 100) / 100) + "m²"
// TSA (Total Surface Area - all 6 sides)
format(round(6 * cbrt(prop("Volume (m³)")) ^ 2 * 100) / 100) + "m²"
// Face Diagonal Length
format(round(cbrt(prop("Volume (m³)")) * sqrt(2) * 100) / 100) + "m"
// Solid Diagonal Length
format(round(cbrt(prop("Volume (m³)")) * sqrt(3) * 100) / 100) + "m"
Each formula in this example contains the mathematical formula for its intended operation.
Next, the operation is run through the round function. We multiply within round() and then divide by 100 in order to round to two decimal places: round(n*100)/100
Finally, we apply the format function to turn the number into a string, allowing us to combine it with its unit of measurement.
