Question

1) a. In deciding if your pick-up truck can handle a load of top soil for the garden, calculate the mass (to the nearest pound) of a cubic yard of soil in your truck bed if the poured soil packs to 1.24 g/cm and is at a gravimetric water content of 0.15. b. Suppose you are returning soil to a hemispherical hole (radius of 30 cm) in your yard. The original soil had a bulk density of 1.45 g/cm, and after filling the hole you have 20 lbs of soil remaining (determined by weighing the left-overs in a bucket without drying). What is the average bulk density of the soil in backfilled hole? You may assume that the soil used to backfill the hole has a 0g of 0.10.
