All these answers are for square objects. How do I find the measurements of a round object, i.e. a cement mixer?
You still get to use your calculator, but you need to use the mathematical formulae dealing with circles.
Area = pi times r squared
Volume of a cylinder = Area (of one end) times length.
For your cement mixer, (Average the diameter for simplicity)
All of the measurements need to be in the same units, lets use inches, then convert it to cubic feet.....
the volume would be:
pi (22 divided by 7)
For my ancient mixer that would be:
22 / 7 x 10" x 10" x 22" = 6,914 cubic inches
1 cubic foot equals 12" x 12" x 12" equals 1728 cubic inches.
6,914 divided by 1728 equals 4 cubic feet.
Now we don't fill it right up, but that is its capacity.
Hope that helps.
By the way, my mixer likes 10 shovel fulls of navvy, 2 shovels of type 10 cement, and about 2 quarts of water to get a nice mix.
I do the water first,
then 5 navvy
then 2 cement
then another 5 navvy,
then just enough water to get the right consistency.
