Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
Where are 12 inch concrete blocks applied?
In general, about half an inch of mortar is required to lay each hollow concrete block. The total amount of mortar needed can be calculated by multiplying this value by the number of blocks to be laid.

Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch

What is a "four inch" hollow block ? ? ? In order to calculate the volume, three dimensions are required . . . length, width, and height. If all three dimensions of this block are equal ... 4 inches ... then the volume is 4 x 4 x 4 = 64 cubic inches.
That depends on the substance from which it is fabricated. A concrete block is heavier than a styrofoam or tofu block with the same dimensions.
