How do I convert square inches to cubic feet?
Well, you have Width, Height and Length, so let's calculate the volume 24" * 80" * 2" = 3840 cubic inches 12*12*12 = 1728 cubic inches = 1 cubic foot Dividing gives 3840 cubic inches = approx. 2.222 cubic feet Now, if you have the weight of some material given as pounds per cubic feet, multiply that value * 2.22 to get an approximate weight.
Conversions involving acre feet?
Ok lets start by breaking this down into what we know... Firstly the feet to mile conversion is 5280 ft = 1 mi So in 10 square miles we have 10 mi^2 = 10 * (5280)^2 ft^2 = 278 784 000 ft^2 This will be used as our total area. Now lets lookup the definition of an acre-foot http://en.wikipedia.org/wiki/Acre-foot An acre-foot is a unit of volume. It has Length, Width, and Depth. So what we are missing is the depth portion. That part is given to use by the annual rainfall, 51.17 inches. Thus we convert that to feet and use it to find our total volume. V = (L x W) x D V = (278784000 ft^2) x (51.17 in)(1 ft / 12 in) V = 1188781440 ft^3 Now we have a total volume we simply compare that to how big one acre foot is. One way to think of this is how many acre-feet can I put into this volume. Thus we use division. We know the cubic feet of an acre-foot is 1 acre-foot = 43560 ft^3 So we calculate by dividing it from our total 1188781440 ft^3 (1 acre-foot / 43560 ft^3) = 27290.667 acre-foot Hope that helps you understand it better...
Volume of a fridge?? Cubic inches and feet?
In cubic inches: It is just 51 x 28 x 28 = 39,984 cubic inches. A cubic inch is just a cube with all sides equaling 1 inch. When you multiply 2 inch dimensions together you get square inchs (area). 3 inch dimensions Multiplied together (L x W x H) gives you cubic inchs (volume) For cubic feet: Just divide all dimensions by 12 (inches per foot) 51 /12 = 4.25 ft 28 /12 = 2.33 ft 28 /12 = 2.33 ft Now do the same as above to get cubic feet (multiply all three dimensions together) 4.25 x 2.33 x 2.33 = 23.14 cubic feet.
How much water will a 3/4 inch by 100 feet pipe hold?
0.306915 cubic feet 3/4 inch is assumed as inner dia of pipe 3/4 x 3/4 x 22/7 x 1/4 x 1/144 x100 = 0.306915 cft.
How do I convert feet to cubic meters and cubic centimeters?
I think you mean the volume is 50 * 25 * 8 = 10,000 cubic feet. There are 2.54 cm per inch. 12 inches per foot * 2.54 cm /inch gives 30.48 cm/ft. To convert this to cubic measures, use (30.48 ^3) cm^3 /ft^3 = 28316.85 cm^3 /ft^3 30.48 cm = 0.3048m, so we get (0.3048^3) m^3/ft^3 = 0.028316846592 m^3/ft^3 Now multiply those two conversion factors by your cubic feet measurement to get: 10 000 ft^3 * 28316.8465 cm^3/ft^3 = 283168465 cm^3 10 000 ft^3 * 0.028316846592 m^3/ft^3 = 283.18 m^3 Square feet is where you multiply say x ft by y ft to get x*y ft^2. This gives you the area of a surface, like the base of a box. If you then multiplied this by the height of the box, say, z, you would have x*y*z, ft*ft*ft = x*y*z ft^3 So, square feet is for area, feet cubed is for volume
