A cinderblock is 8" by 16" if you include the mortar joints.
You'll need to figure out how many square inches the cinder block is (8 X 16)
and how many square inches the wall is. (1 square foot equals 12" x 12")
Divide the size of the blocks into the size of the wall and that's how many blocks you'll need.
You'll also need to start doing your own homework.
Getting people to do it for you on-line is the same as cheating.

970 pounds EACH? I'm not buying it; the blocks would weigh 202 pounds per cubic foot and the concrete a block this big is made from only weighs 150 pounds per cubic foot. But set that aside. This isn't a question you can get a real answer to, because I need to know how the wall is shaped. If you're building a straight wall, you'll need to build supporting structures because if you just throw a wall 30 feet high up it'll fall over in the slightest wind. If you're building a wall that encloses an area, the wall would be self-supporting. Let's first calculate the number of blocks in one course. Multiply the length by 12 to get the inches, then divide by 32...or 1500. Next is the height. The same formula gives us 22.5 blocks. Unless you plan to saw 750 blocks in half, the height will be 33 blocks or 30 feet 8 inches. The total will be 49,500 blocks. And the weight is 48,015,000 pounds - not counting the mortar. That's 1200 truckloads.
Well, there are many things that need to be considered before you can accurately estimate the cost of building a concrete patio. Firstly, depending on where you live, a building permit may be required and could be expensive. Also, the material you buy depends on your area's climate. For example, if your ground freezes during the winter you will need to buy a special kind of concrete mixture. Ultimately, the cost varies per person/place.
The number of rectangles you can build with a prime number of tiles depends on many factors such as shape, size, and uniformity of the tiles.

To calculate the number of concrete blocks needed for a building, you first need to determine the area of one block and then divide the total building area by the block area. Concrete block sizes vary, so you will need to know the dimensions of the block you plan to use. Once you have that information, divide the total building area (25x30) by the block area to find the number of blocks needed.
The answer will depend on the size of the concrete block!
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
most houses are made from re-inforced concrete and terracotta hollow blocks sometimes concrete
More info needed. There are so many sizes of concrete blocks. Different industries use different sizes. 6 x 2 x 10 is just ONE size.
The best estimate on this is to double the number of bricks you'd need for a single garage, divide this number by 3 and then multiply the result by 1/3 the square root of 81.
No,in both cases same amount of money is spented,bcoz concrete also uses brick to build
All depends how high you want to build the walls. You'll have to decide that before you start.
They used concrete.
depends on the bridge type really. most are steel and concrete.
