An archeologist finds a huge monolith in the desert. In order to estimate the weight of this object; he estimates the dimensions of the monolith and removes some chips from the rock with his hammer, collecting the following data:dimensions of the monolith = 1.5 m × 5.2 m × 13 mmass of rock chips = 41.73 gvolume of rock chips = 15.2 cm3Determine the mass of the monolith in pounds, assuming it is of uniform composition. (1 lb = 453.6 g)
