Standard studs are spaced 16" apart. 30 feet times 12 inches = 360 inches. 360 inches divided by 16 inches = 22.5. If you are measuring left to right, the right-side stud from the frame becomes the last one. Depending on how you will compensate for the extra 8" at the end, you will need 21 or 22 2x4s.
144/8 = 18
There are different sizes of brick. You will need to know how many bricks are in a square foot, including the mortar joint.
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.
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.

They are usually 16" spacing on 2x3.
a linear yard is one yard long - you need to know how wide the covering is in order to compute how much covers a square foot wall
You would need to walk/run up to the wall which ever you choose.... and then this is the tricky bit you will need to lift your foot for the ground ( this means the you will have to balance on one foot for a second) and then with the foot off the ground you move it back and then forward once when you go forward you will need to keep on going until you hit the wall. there you have successfully done a 'wall kick'. :-)

there are 12 studs and 11 spaces in a 14' wall

The distance around the wall is 42 linear feet.
on a wall it would be 100 square feet.
All you do is multiply 9 by 9 ...
