The density of a substance is usually measured in weight units per volume (for example, per cubic foot), not per area. For a square foot... it would depend how thick the slab of granite is. That may vary between different manufacturers.

Let's assume that the density of marble is 2.76 gm/cm3. Marble varies somewhat in density depending upon the type of marble; so your marble may vary from this number. 0.75 inch X 1 square foot X 144 square inches/square foot = 108 cubic inches 2.76 gm/cm3 X 16.39 cm3/cubic inch X 108 cubic inches = 4886 gms 0.00220 pounds/gm X 4886 gms = 10.7 pounds
144 square feet

On average, a granite countertop can weigh around 18-24 pounds per square foot depending on its thickness and size. It's important to consider the weight-bearing capacity of your cabinetry and support structures when installing a heavy granite countertop.
The cost will vaey on size on your counters and kind of granite. It is about $4.00 per square foot, for black granite 3/8" thick for materials only.
On average, an inch of granite weighs around 12-13 pounds per square foot. This weight can vary slightly depending on the specific density and composition of the granite.
Granite is figured at 168 pounds per cubic foot. If you know the thickness, you can determine the weight per square foot.

The weight of a square foot of bronze would depend on its thickness. On average, a square foot of bronze that is 1/8 inch thick would weigh around 1.5 pounds.
Granite is figured at 168 pounds per cubic foot. If you know the thickness, you can determine the weight per square foot.
Just short of 11,000 pounds roughly. Average density of granite is about 2.7 g/cm3.
That depends on how much of it you have!One pebble doesn't weigh very much, but a cubic foot of granite weighs 168 pounds! Compare that to water, which weighs about 62 pounds per cubic foot.
