Question

Calculate the density of a substance in pen-
nyweights per peck that has a volume of .321
hogsheads and a mass of 35.36 kg.
1 pennyweight = 1.55 grams
1 hogshead = 238.5 liters
1 peck = 9.091 liters. Answer in units of
pw=pk.

Answer 1

Why aren't you Americans using metric yet?
Drag yourself into last century already!

Answer 2

m= 35.36kg = 35360 grams
= 35360 / 1.55 = 22813 pw

V= 0.321 * 238.5 = 76.56 liters
=76.56 / 9.091 = 8.42 pecks

density = m/V = 22813/8.42 = 2709 pw/pk
