A concrete masonry unit is tested for compressive strength and produces the following results:

            Failure load = 120,000 lb

            Gross area = 130 in2

            Gross volume = 960 in3

            Net volume = 447 in3

Is the unit categorized as solid or hollow? Why? What is the compressive strength? Does the compressive strength satisfy the ASTM requirements for load bearing units shown in Table 8.2?
