How much does a regular building brick or block weigh?

(3-3/4" x 2-1/2 x 8)\nstandard (common) red brick = 5 pounds \n(density = 1922kg/m³ or 3,239.64 lb/cubic yard)\n\n(8 by 8 by 16) \nconcrete block = approx 26 lbs\n\n(density of SOLID concrete = \napprox 2200kg/m³ or 3,708.2 lb/cubic yard)

It's about 10 lbs per square foot. (Multiply the density of steel, about 490 pounds per cubic foot, times the thickness of the plate in feet, 1/4 in. = .02 ft.) I'm assuming you mean 1/4 in. plate.

Mass. I think.Depending on how strong the gravity is your mass changes.

A stone is a unit of mass within the Imperial units system used in the United Kingdom and Ireland, and formerly in a number of Commonwealth countries. It is equal to 14 pounds avoirdupois, i.e. 6.35029318 kilograms.\n\nA unit of weight in Great Britain; equal to 14 pounds.

The density of glass is around 2.3 gm/cc or 0.85 lb/in^3.  To get the  pounds per square foot,  Multiply the thickness in inches by 12.  So a 1/8" thick piece weighs 1.5 pounds per square foot.

Each mix design for concrete will vary the weight and density of the mix. Air entrainment, water to cement ratio, coarse stone% and fine aggregate%, cement content, admixture content, fly ash substitution all contribute to the variation in weight. I do agree that 150 lbs per cubic foot is a recognized average when calculating concrete weight. since there is 27 cubic feet in a cubic yard, (150 lbs x 27 cubic feet) one cubic yard equals 4050 lbs or 2.025 english tons.

A stone is a UK (United Kingdom) measure of weight. 14 pounds equals one stone

It makes very little difference assuming equal thicknesses, because the insulating factor for both wood and brick are very poor. How much "good" insulation you have in each case makes the difference. Materials like fiberglass are three or more times more effective than either wood or brick. \n\nAs a side note. Most house today are not made of brick but only have a brick veneer over a wood frame.

I'm guessing by clay blocks you mean brick masonry fired in a kiln.  They are manufactured with holes in them but that is usually to reduce weight; however, I have seen arch lintels use the holes for reinforcing.\n\nToday's buildings usually use hollow concrete masonry (cinder blocks).  In terms of horizontal reinforcing, these types of blocks are manufactured in what is known as a bond beam.  This allows for horizontal bars to be set in a u-shaped profile which is then grouted.\n\nNot sure if that helps, maybe be more specific?

Sure...\n\nRWRWRWRWRW\nWRWRWRWRWR\nRWRWRWRWRW\n\nHowever, it requires you to stack the opposite color bricks on top of each other like a checkerboard, and *not* to stagger the bricks.  This wouldn't be your typical brick wall and wouldn't be very strong.\n\nIf it requires staggering, you can see that if you put two different color bricks down next to each other, there is no way to stagger a brick between the two unless you add a 3rd color.

The net force is zero.  Remember the equation F=MA:  force equals mass times acceleration.  If something is at rest, A is zero, so F must be zero.\n\nThe gravitational force on the brick is exactly balanced by the force of the table holding the brick up.  Net force is zero.

A "stone" is also 14 pounds, but no one uses that unit of measurement anymore.  It was the "Imperial" British system.\n\nOne stone is 6.350 kilograms.

yes it is a british weight measurement equivalent to 14 lbs. i still use it i would allways say my weight in stones opposed to lbs.

Depends where you are.  Not all city blocks are the same.  In Manhattan, 20 street blocks = 1 mile, but 5 avenue blocks = 1 mile.  In Boston the size of the blocks are totally random.

well some say 12 - 15 pounds...guess it  depends on what you have in it

ok, i'm assuming that the block is being hung into water. otherwise the problem's too easy.\nso 1.00x10^-3 m3 of water will be 1 kg, or 9.8 N. thus block weighs 19.8 N or 2.02 kg.\nThen, 2/3*1.00x10^-3 = vol of unknown liquid displaced = 6.67x10^-4 m3. since its floating, we also know that amount of liquid weighs 19.8N, or 2.02 kg, so 2.02kg/6.67x10^-4 = 3.03x10^3 kg/m3\nI hope that's right.

The average city has from 15 to 20 blocks per mile, which would mean they range from 264' to 352' feet long.  (5,280/20 = 264', 5,280/15 = 352')  However, there is no standard measure of a "city block".\n\nBut using these ranges, you would have somewhere between 2.84 and 3.78 blocks in 1,000 ft.  Rounding, that is between 3 and 4 blocks.  Your "guestimate" is within this range.
