How many bags of concrete cement shoud I use?

Question

Hello, I need to make square out of concrete. Square dimensions are 3x3 meters. Height is 0.3m and width 0.15m. So it is around 0.54 cubic meters.

Cement bag weight 40kg. I need to mix it with a ratio of 1:4 with sand. So with one bag of cement I got roughly 200kg of mass (40+40*4). How many bags of cement should I use to make this square?

Answer 2

In Anglicanism, Eastern Orthodoxy, Catholicism, Old Catholic, Oriental Orthodoxy, Lutheranism, and some other churches, holy water is water which has been sanctified by a priest or bishop for the purpose of baptism or for the blessing of persons, places, or things. Holy water is water that has been blessed and set apart for baptism. It is also used as a sacramental. Holy water is kept in the font, the church furnishing used for baptisms, which is typically located at the entrance to the church (or sometimes in a separate room or building called a baptistery); its location at the entrance serves as a reminder of the centrality of baptism as the primary rite of initiation into the Christian faith. Smaller vessels, called stoups, are usually placed at the entrances of the church. As a reminder of baptism, Roman Catholics dip their fingers in the holy water and make the sign of the cross when entering the church. The liturgy may begin on Sundays with the Rite of Blessing and Sprinkling Holy Water, in which holy water is sprinkled upon the congregation; this is called aspersion, from the Latin, to sprinkle. This ceremony dates back to the ninth century. An aspergill or aspergillum is a brush or branch used to sprinkle the water. An aspersorium is the vessel which holds the holy water and into which the aspergillum is dipped. Salt may be added to the water "where it is customary."

"Square dimensions are 3x3 meters. Height is 0.3m and width 0.15m."



You say the square is 3x3 but then it's width is 0.15?

Wouldn't the width be 3m?



3x3m @ 0.3m high is 2.7 cubic metres

Answer 4

Idk if I'm wrong I think about 20 bags or more
