It depends on the thickness of slab. A yard of cement contains 9 cubic feet. Thus, it would cover 9 square feet if the slab was 1 foot thick. For a 4 inch thick slab, it would cover 3 times as much area, or 27 square feet.
It would be helpful to have units of measurement in the equation. However, pouring a slab I'll presume your measurements are feet x feet x inches. The volume of this slab is 55 x 15 x 0.5 (6 inches is 0.5 ft) = 412.5 cubic feet 1 yard of cement (more likely concrete as a cement slab will crumble under load) is equal to 27 cu.ft. So, 412.5 cu.ft. needed / 27 cu. ft. / cu. yd. = 15.2777...cu. yards. you will need to order 15.27777...cu. yards, as a yard isn't sold in this decimal you will need to order 15 1/2 yards of concrete to pour your slab.
1 square yard = 9 square feet
depends how deep
Here's a link to a great concrete calculator that will compute that for you!
You'll need 1 cubic yard.
one yard of cement will make a 8 x 10 square foot slab at 4 inches thick, that's 80 sq. feet per yard of cement at 4 inches thick.

14 x 14 x 3/12 = 49 cubic feet / 27 = 1.814814... cubic yards.

Oh, isn't that a lovely question! In a cubic yard, you can typically fit around 13-14 bags of cement, depending on the size of the bags. Just imagine all the wonderful things you can create with that much cement - it's truly a painter's dream!

Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.

The question does not provide units of measure which are important in answering the question. However, it is likely that the slab is 1400 square feet and that the slab thickness is 3 inches. A cubic yard of concrete is 3 ft by 3 ft by 3 ft, or 27 cubic feet. To solve the problem, you convert the slab size into cubic feet by multiplying the length in feet by the width in feet (to get 1400 square feet) by the thickness of the slab in inches divided by 12 inches per foot or 1400 * 3 / 12 = 350 cubic feet. To convert to cubic yards, divide the 350 cubic feet by 27 cubic ft/cubic yard to get 12.96 cubic yards. So, order 13 yards of concrete.
