What is reasonable prediction for the number of times an even number will be rolled in 10000 trials?
For a regular cubic die, a reasonable point estimate is 5000.
How do you calculate how many bags of concrete for a 11x11 slab?
To calculate the number of bags of concrete needed for an 11x11 slab, first determine the volume of the slab by multiplying its length, width, and thickness (in feet). For example, if the slab is 4 inches thick, convert that to feet (4 inches = 0.33 feet) and calculate the volume: 11 ft x 11 ft x 0.33 ft = 40.13 cubic feet. Next, convert cubic feet to cubic yards (1 cubic yard = 27 cubic feet), which gives you approximately 1.48 cubic yards. Finally, if each bag of concrete covers about 0.5 cubic feet, divide the total volume by the coverage per bag to find the number of bags needed: 40.13 / 0.5 = about 81 bags.
Calculate the number of cubic yards of concrete needed for the cellar floor in a 30 ft x 40 ft house using accurate methods The slab is 3 in thick Show all work?
1 cubic yard = 27 cubic ft3 inches = 0.25 footThe volume of the slab is (30 x 40 x 0.25) = 300 cubic ft= (300 / 27) = [ 11 and 1/9th ] cubic yards = 11.111 (rounded, repeating)
How many cubic yd in 336 square ft 6 inches deep?
336 square feet X .5 feet = 168 cubic feet 168 cubic feet / 27 cubic feet per cubic yard = 6.22 cubic yards.
How many yards of material of dirt is in 2 inches of material from 40ft X 40ft area?
First of all divide 2" by 12" to get 0.1666 feet; then multiply 0.1666' x 40' x 40' which equals 266.56 cubic feet; Multiply 266.56 cubic feet x 0.03704 to get 9.8734; Therefore, 2 inches of topsoil from an area 40 feet by 40 feet = 9.87 cubic yards. Hope that helps. The number 0.03704 is purely a conversion rate for cubic feet to cubic yards.
