cbrt
Learn how to use the cbrt function in Notion formulas.
1
cbrt(number)
The argument is
where:
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
