The Least Common Multiple (LCM) of 12, 3, and 24 is 24.
1/3 and 3/8 have a lcd of 24 (8/24 and 9/24)
the least common multiple of 3,4 and 8 is 24.

1. average height: 50 feet 2. average length: 24 feet 3. average weight: 20 pounds
The volume of a 8inx8inx16in block is 1024in^3 or .59259ft^3. I would assume that steel is used for the reinforcing. The density of steel varies from 484 to 503 lb/ft^3 and the density of concrete varies from 109.25 to 149.83 lb/ft^3. So assuming that the steel reinforcement accounts for 6% of the volume then the weight of the steel would be greater than 17.21lbs (.59259ft^3*0.06*484lb/ft^3) and less than 17.88lbs (.59259ft^3*0.06*503lb/ft^3). The concrete would then account for 94% of the volume and its weight would be greater than 60.86lbs (.59259ft^3*0.94*109.25lb/ft^3) and less than 83.46lbs (.59259ft^3*0.94*149.83lb/ft^3). So with all of these assumptions the block would weigh between 78.07 and 101.34lbs.
you need to have the density of the concrete block. after you find it, use the formula density = mass/volume --> mass = density x volume to calculate the mass. if you want to find the weight in Newtons, use W = mg where m is the mass and g is 9.81N/kg. that will give you the weight of the block. for this case, the volume is 4m x 8m x 16m ( i assume it is in metres cos no units were given) = 512m^3. find the density in kg/m^3 and use the above formula mass = density x volume to calculate the mass. use W = mg to find the weight of the block in Newtons.
Really depends on what the block is. If it solid, 2 core, 3 core, lightweight, midweight, concrete? Is it split face, fluted or burmished? Alot of different factors in determining that anwser. Also it depends on where its made, every block plant makes them a little different. But for a general reference a regular Block weighs about 40 pounds.
The weight density for concrete is 156 lb/ft3 and the volume of the box is 3 ft3 if you multiply both number you can find the weight. Total weight is 468 lb.
3 pound
Weight:6.5 to 24 lbs (3 to 11 kg)
A block has a mass of 550 g and a volume of 650 cm 3 . What is the block's density, and will it sink or float in freshwater?
You need 1.16tonne. You need to know the weight of a bag of concrete and then divide 1.16 by that weight and that will give you the answer you need.
Spacer's will make it easier for the "First Time Mason". It will keep the Joints at the standard 3/8 inch.
For design consideration Reinforced concrete is 150 lbs/ft^3. Unreinforced is around 145 lbs/ft^3. That comes out to 2402.77 kg/m^3 and 2322.68 kg/m^3 respectfully
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
The ones that I see are 2-3/8" thick and 6"x12" in size.
