How many 5p in a cubic foot?

To determine how many 5p (5 pence coins) fit in a cubic foot, we first need to know the dimensions of a 5p coin. A 5p coin has a diameter of about 18.0 mm and a thickness of about 1.7 mm. A cubic foot is equivalent to 28,316.8 cubic centimeters. Assuming an approximate packing density, around 10,000 to 12,000 5p coins can fit in a cubic foot, but the exact number may vary based on the arrangement and packing efficiency.
