The number of concrete blocks that make up a foot depends on the size of the blocks. Standard concrete blocks, often referred to as cinder blocks, typically measure 16 inches long, 8 inches high, and 8 inches deep. To cover a linear foot, you would need about 0.75 of a standard 16-inch block to reach a total of one foot in length.
one foot for each foot of perimeter.
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.
Okay, this requires a little simple math and some three dimensional thinking. For the fence (wall) planks alone, you will need 55 eight foot 2 x 4's. For a simple box frame you will need another 8. 55 + 8 = 63 The problem is, the fence (wall) will not be free standing. You'll need three twelve foot 4 x 4 posts (twelve foot long, because four feet of them will be set into the ground.
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.

All depends how high you want to build the walls. You'll have to decide that before you start.
For a 4-foot fence, you should use 5 to 6-foot t-posts.
If you have a fenced in yard (NOT CAIN link fence) or have 2 or more people make a foot- foot fence.
streach it der are you stupid or what god save me
A 2 foot fence it tall enough.

A four to five-foot fence is sufficient, if it's just for cows. If you want to keep deer as well, you will need a six-foot-tall fence.

You need 1962.5 fence posts.
A fence post for a 4-foot tall fence should be buried at least 2 feet deep to ensure stability and support.
