cubic capacity is pye X radius squared X depth
that is 3.1416 X 5.33 squared by 1 .3 ft
that is 3.1416 X 28.408 X 1.3
that is 118.69 cubic ft
1 cubic ft = .0370 cubic yards
multiply 118.69 cubic ft =4.39c yards or you can convert the feet to yards first and then apply the formula
so that is 3.1416 X 1.77 squared =
3.1416 X 3.13= 9.83 sq yards X .43 yards =4.22 cubic yards
the difference is from how many decimal points you go to
for each number
Assuming that 20x12 means 20 feet by 12 feet, then you take the three values in feet - 20, 12, and .333 (4 inches is 1/3 foot).
Multiply these three numbers to get the cubic feet:
12 x 20 = 240
240 x .333 = 79.92
Now that you have 79.92 cubic feet, to get cubic yards you divide by 9 since there are 9 cubic feet per cubic yard.
79.92 cu. ft. divided by 9 = 8.88 cubic yards (round up to 9).
multiply the length (100 ft) by the depth (1.5 ft) by the width 2 ft and that results in a cubic ft measurement
divide that by 9 ( 9 cubic ft = 1 cubic yard ) and you have your answer
I am not going to work it out for you as it is grade 3 maths
Hi Bob:
1 cubic yard is 3ft by 3 ft by 3 ft.
3 times 3 times 3 equals 27, so
1 cubic yard equals 27 cubic feet.
2 1/2 inches divided by 12 inches equals .2083333 feet
196 square feet times .208333 feet equals 40.83333 cubic feet
40.83333 cubic ft divided by 27 cubic ft equals 1.5123456 cu yards.
Ta Da!!!!
AC is approx. 145 lbs per cubic ft.
there are 27 cubic ft in 1 cubic yard
60 tons x 2000 = 120000 divided by 145 = 827.58 cubic ft divided by 27 = 30.65 cubic yards
square yards would depend on thickness of AC.
you can take thickness x sq ft to get cubic ft
in concrete 1 cubic yard =
4 inch thickness = 81 sq ft or 9 sq yrds
6 inch thickness = 54 sq ft or 6 sq yards
You don't. Square feet is a measure of area while cubic meters is a measure of volume.
Consider a room 8 ft by 10 ft. The floor area is 80 square ft. What's the volume of the room in cubic feet (let's not worry about converting to meters yet). Well, that depends on the height of the ceiling, doesn't it? If the ceiling is 8 ft high then the volume is 640 cubic feet. If the ceiling is 12 ft high then the volume is 960 cubic feet. Without that third dimension, you can't calculate the volume.
If you want to calculate the volume of an object and have the answer in cubic feet.
Volume=Length X Width X Height With the dimensions you give Volume=12.5in X 37in X 20in Volume=9250 cubic inches
To convert 9250 cubic inches into cubic feet you need to understand that there are 1728 cubic inches in 1 cubic foot. L X W X H = 12"X12"X12"=1728 cu in
You then multiply 9250cu in and (1/1728cu ft) Really you are dividing 9250 by 1728. your answer is 5.35 cubic feet.
12 inches in 1 foot 144 square inches in 1 square foot 1728 cubic inches in 1 cubic foot
to convert you put the unit you want to keep on top of the dividend. to conver to to feet ( randomly selecting 100 inches) Example converting 100 inches to feet
100inches X ____1ft____ = (100/12) = 8.3 feet 12inches
or cubic inches to cubic feet 4000 cubic inches to cubic feet
4000cu in X ____1cu ft____ = ( 2.33 cu ft) 1728 cu in
if you notice that the units on top and bottom of the dividend cancel each other out leaving the numerator (top number) as your unit. it also works in reverse
2.33 cu ft X ___1728 cu in____ = (4000 cu in) 1cu ft
