That depends, 3 tons of what. Specifically, you would have to know the density of your substance, and how thick you will cover whatever you want to cover.
To find out how many feet a ton of limestone would cover at a depth of 4 inches and a width of 8 feet, first convert the depth to feet (4 inches = 1/3 foot). A ton of limestone is approximately 1.5 cubic yards, which equals about 40.5 cubic feet. The volume covered can be calculated using the formula: Volume = Width × Length × Depth. Rearranging gives Length = Volume / (Width × Depth). Plugging in the values, Length = 40.5 cubic feet / (8 feet × 1/3 foot) = 15.1875 feet. Therefore, a ton of limestone would cover approximately 15.2 feet long at the specified depth and width.
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
It depends on what size/kind of rock you want to use. Let's start with what I'll assume is the largest rock one would use in a rock garden - 3 to 5 in. River Rock: 1 Ton will cover about 80 sq. ft. if you want to make sure there are no "holes" 1 to 3 in. River Rock: 1 Ton will cover about 100 sq. ft. (no holes) 3/4 in. Rock: 1 Ton will cover about 150 sq. feet at 1.5" deep... & 120 sq. ft. at 2" deep 3/8 in. Rock - or crusher finds cover about the same as 3/4 in. Rock, but when using smaller rock, I like to cover at least 2" deep because there's more of a tendency for smaller rock to move around & settle, and you want to make sure you aren't looking at the weed barrier in half a year.
it will cover 3 cubic feet, or 9 feet, I am not sure how many square feet
Based on sand and gravel calculator found on L.R. Faulk Construction Co. site, 1 ton of gravel (clean rock) will equal approximately 7.3 sq. ft x 6 inches deep, or 5.2 sq. ft x 3 inches deep. A ton of gravel will cover approximately 15 square yards (135 square feet) at 3 inches deep.
3 ton
3 feet x 3 feet
Average of about 1500-2100 sq ft. Please be aware that there are a lot of factors, such as ceiling height, insulation, climate, shading, etc. that will affect this.
The unit is a 3 ton and the rule is 400 square feet per ton. The answer would be no as it would be a better fit for a 1200 square feet home.
How much dose 3 square of roofing cover
A bundle of Shingles will cover roughly 33 square feet. A square of Shingles (3 Bundles) will cover 100 square feet.
There are many variables but 3 tons of air conditioning is enough to cover 1750 sq ft.
