1st off, David W converted your kg of dirt to grams since that was the

base unit in your original comparison of 920 grams to 8 inches of dirt

David W then set up a proportion using 920 is to 8 as 48,300 is to d

******************************************************

Another way to work this problem is to take the original information

that 920 grams of dirt filled 8 inches and find the "grams per inch"

920/8 = 115 grams/inch

(48,300 grams)÷(115 grams/inch) will give us the answer

48,300/115 = 420 inches
