Each type of wood has a different weight per unit volume. Some commonly used kinds of wood are pine, fir, spruce and cedar. Pine weight ranges from 27 to 45 pounds per cubic foot. For one cubic meter, multiply by 27. Douglas fir weighs about 33 pounds per cubic foot. Spruce (dry) weighs 28 pounds/cubic foot. Red cedar weighs 24 pounds/cu. foot.
You can't-lb per cubic foot is a measurement of pressure, tonnes is measure of weight. You could convert Ib per cubic foot to tonnes per cubic foot or more usually, gram per cubic centimetre but not lb per cubic foot to tonnes
80 lbs per cubic foot
Granite is figured at 168 pounds per cubic foot. If you know the thickness, you can determine the weight per square foot.
About 100 pounds per cubic foot
Typical window glass weighs 156 pounds per cubic foot. For comparison, a cubic foot of aluminum weighs about 168 pounds, and a cubic foot of oak is around 50 pounds.
Granite is figured at 168 pounds per cubic foot. If you know the thickness, you can determine the weight per square foot.
Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.

A cubic foot of water weighs aprox. 62.42796 pounds, 28316.847 grams, or 28.316847 kilograms. Here is some additional information from http://ga.water.usgs.gov/edu/waterproperties.html * Weight: 62.416 pounds per cubic foot at 32°F * Weight: 61.998 pounds per cubic foot at 100°F * Weight: 8.33 pounds/gallon, 0.036 pounds/cubic inch * Weight: 1679.616 pounds/cubic yard, based on 0.036 pounds/cubic inch * Density: 1 gram per cubic centimeter (cc) at 39.2°F, 0.95865 gram per cc at 212°F
Concrete averages in weight between 90lbs per cubic foot to 140lbs per cubic foot. Knowing that its a simple equation. L x W x H = C x W. in this case 800 cubic feet. So basically the slab can weight between 72,000lbs and 112,000lbs. Length x Width x Height = Total Cubic Feet x Weight per cubic foot = Total Weight
