Civil Engineering Materials #$8\mathrm{.}3$

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

Failure load:$120,000$ lb

Gross are $=130$ in$^2$

Gross volume $=960i{n}^3$

Net volume $=447i{n}^3$

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 $8\mathrm{.}2?$
