Question about Strawganic Steel Rainbow Straight
How much ml does it hold?
radius² × pi = base area
(1.5mm)² × pi = 7.07mm²
footprint × height = volume
7.07mm² × 215mm = 1519.75mm³
1 cubic millimetre = 0.001 mililitre
1519.75mm³ : 1000 = 1.52ml
The 3mm inner diameter is only an estimate. Therefore, the reality may be slightly different. But there should be room for between 1.2 and 1.7 mililitres in the straw.
