To determine how many slabs of stone you need, first convert the area from square feet to square inches. Since 1 square foot equals 144 square inches, 133 square feet is 133 x 144 = 19,152 square inches. Then, divide the total area by the area of one slab: 19,152 ÷ 40 = 478.8. Therefore, you would need 479 slabs of stone to cover 133 square feet, rounding up to the nearest whole slab.

To cover a 30x30 area, which has an area of 900 square feet, you would need to determine the area of one 12x12 stepping stone, which is 1 square foot (12 inches x 12 inches = 144 square inches, or 1 square foot). Therefore, you would need 900 stepping stones to cover the entire 30x30 area.
Well, you would take the 7000 square feet of dirt and multiply it by the four inches of stone to get the 28000 cubic yards of stone. (28000 yds³)
"4 inches" is a length. "7676 square feet" is an area. "4 inches by 7676 square feet" describes a volume, which is equal to 2,558.67 cubic feet. (= 7676/3, because 4 in = 1/3 ft.) So your question is better put as "How many tons of crushed stone does it take to cover an area of 7676 square feet to a depth of 4 inches?" The answer depends on the density of the crushed stone. I can't answer that, but I've given your question a clearer phrasing.
The 4 inches is 4/12 of a foot or 1/3 foot. Length times width times height is the volume, so 2856 (the area in square feet) times 1/3 (the depth in feet) = 952 cubic feet.

However much you want. By suitably varying the thickness, you could, in theory cover the surface of the earth or even a larger area.The 'square feet' of area that it covers is 324/(depth in inches)
What is a prehistoric English site of tall, huge stone slabs? I believe he was asking the name of tall, huge stone slabs located in the UK...the name is Stonehenge

A square foot will cover a square foot, regardless of the depth of the material the cover is made of.

Not sure what 2b is but crushed concrete with 1 1/2" rock will cover about 60 square feet. 15 tons ends up being around 12 cubic yards.
