To determine how many 80 lb bags of cement are needed for a 5x7 area that is 4 inches thick, first calculate the volume in cubic feet. The volume is 5 ft × 7 ft × (4/12) ft = 11.67 cubic feet. An 80 lb bag of cement typically covers about 0.6 cubic feet, so you would need approximately 20 bags of cement (11.67 ÷ 0.6 ≈ 19.45). Therefore, you would need 20 bags to complete the project.
Cement comes in bags that weigh 94 lbs. The volume of the bag is approximately 1 cubic foot. If you want to mix concrete which is a mixture of a coarse aggregate (gravel) and a fine aggregate (sand) and something to bond the two aggregates together (cement) then firstly you need to know the strength concrete that you require. For 1 cubic yard of 3000psi (pounds per square inch) strength you will need about 6 bags cement 12 cubic feet of sand and 24 cubic feet of gravel. Rule of thumb is the ratio should be 1:2:4 (cement:sand:gravel)

Assuming you meant redimix concrete (cement is just a portion of concrete, although some people use the terms interchangably), and you are needing 1.5 cubic yards (total size 3 feet by 3 feet by 6 feet) you would need about 5400 pounds of it, adjusting for waste. 5400 lbs is 90 bags at 60 pounds each or about 68 bags at 80 pounds each. If you are pouring a 4" slab that is 1.5 square yards, you need about 600 pounds. (you can do the math on the number of bags. I went through similar calculations when I was planning to pour a front walk and decided to order it and have it dellivered. I know this seems like a lot, but you can confirm it yourself. Quikrete is one brand of redimix, and they have a nifty calculator on their site to calculate how many you need. See www.quickrete.com/calculator/main.asp If you truly meant "cement", then it would depend on your proportions of aggregate (sand, stone, etc) to cement that you choose for your concrete.
10 bags will give you 6'2/3", seven bags will give you 11 bags will give you 7'1/3". Each bag is 2/3 cu feet.
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
At least several hundred, maybe more than a thousand, and it'll never have the strength you want. You'll be better off if you can get ahold of some of the cement too.
Best guess: 17 bags (80lb bags) with a third of a bag being left over. This is for Quikrete.

The answer depends on the size of the cement blocks which are not an international standard.
9.72 Cubic Yards of Concrete is required, if you are going to order by cement truck. 874.8 bags of 40# (40 lbs) bags, or 583.2 bags of 60# 437.4 bags of 80#
For 1 meter cube of brick work, you would need approximately 13 bags of cement.
at present condition 10*10 room how much bricks and cement and iron rod and blue stone Required
well do to my calculations i made is that it is 6 or 18 feet long

For M25 grade concrete, the mix proportion is typically 1:1:2 (cement:sand:aggregate). This means for 1 cubic meter of concrete, you would need 1/4 cubic meter of cement. As 1 cubic meter is equivalent to 35.32 cubic feet, and one bag of cement usually covers around 0.035 cubic meters, you would need approximately 7-8 bags of cement for 1 cubic meter of M25 grade concrete.
Heat transfer from the cement to your feet can occur through conduction. When you walk on the cement, heat from the cement is transferred to your feet by direct contact. Cement is a good conductor of heat, so the transfer occurs quickly.
