What is the volume of a penny coin?

Answer 1

The current British Penny (1992 to present) is -

20.3mm in diameter (radius = 10.15mm) and is 1.65mm thick (height).

Volume = Height x Pi (Radius x Radius)

Volume = 1.65 x 3.14 (10.15 x 10.15)

Therefore the volume is a smidgeon greater than 534 cubic mm.
