Math question

Does 1 cubic foot times 3 wind up equalling one cubic yard, or am I oversimplifying?

1 cubic foot times 3 equals 3 cubic feet. A cubic yard is 27 cubic feet.

1 cubic foot times 3 equals 3 cubic feet. A cubic yard is 27 cubic feet.

Agreed

Picture the cubes you would have to add, maybe that helps.

 

[MagicFingers]

Picture a cube, not just one side of one layer

Volume = side length, cubed
or 3' times 3' times 3'

In my demolition business I figure buildings as a cubic foot when crushed to small pieces yhen divide by 27 to convert to yards,then add 30% swellage and divide by 25 this gives me a total landfill cost and trucking cost.

Your oversimplifying!

As everyone else explained!

think of a cubic yard as a box that is a yard long in length, width, and height. therefore it is 3' x 3' x 3', which equals 27. therefore 27 cubic feet.

now, convert that to a cubic meter.

This is a trick question. Everyone knows that cubic meters only take euros or Canadian money.

now, convert that to a cubic meter.

1 cubic yard = 0.764554861 cubic meter.

Just remember cubic means three dimensions: height X width X depth; and each dimension has to be the same size to give you a cubic yard or foot or whatever.

As for converting cubic yards to metres that's what God made engineers (and the internet) for!

Besides, in this day and age, who measures in imperial!

we schmucks in america do.

scalywag's right though... the dimensions don't have to be the same. if volume only represented the measurment of a container with equal dimensions, the only objects there could be volume for are spheres and cubes.

 

[Straight-8]

I'm sorry bro...but they don't have to be the same size. They do have to be the same unit (foot, yard, meter, inch, etc) The value of the unit can be different though.

Oops, too true ! For the sake of visualization I was trying to make it simple but of course you could have a 1'X1'X27' cubic yard; but to get to there you have to know the number of cubic feet in a cubic yard and THAT is what I was inarticulately trying to help the original poster with: calculating the volume of a cubic yard in the abstract. Thanks for catching it.

I heard that the only 'official' weights and measures standard in the US was passed in the early 19th century and it was metric...which stands to reason given that you guys borrowed your whole system of government from France. I don't know if the story is true but it strikes me as a fine example of the 'yankee' spirit (in a positive, independant way) that they ignored this bureaucratic directive and just carried on with what worked...but it does leave you a bit out of the loop now!

Actually, there is an entire bureaucracy (Bureau of Standards) headed by a highly-paid political appointee (Sealer of Weights & Measures). There's an old anecdote about a journalist who had the temerity to ask what the Sealer actually did.

"Howthehell should I know?" the workfare recipient du jour snapped. "I've only had the job for three years!"

A Sq. yard is

Hmmm, I'm getting 1 cubic yard = 0.764554857984 cubic meter

I'll have to try again tommorrow once the alcoholic beverages wear off.

0.000207 acres
8361.27 sq.cm
9 sq.ft.
8.99996 sq.ft.(USsurvey)?
1296 sq. in.
.8361 sq meters
3.228 x 10 neg seventh Sq miles
0.03306 sq rods
and no one cars about chains and links, do they?
1 sq meter = 1.19599 Sq Yds.

 

[Straight-8]

1 sq meter = 1.19599 Sq Yds.

Jeez don't confuse a volume discussion with an area calculation or we'll really end up lost!

Oops, sorry, got off onto squares, not cubes

You know, being anal about this, the 1'x1'x27' figure would not have ANY cubic feet at all, for a cube must have 3 dimensions, not 2. It would have 27 SQUARE FEET. or would it?....
Doesn't a cube, by definition, have 3 equal dimensions, h, l, w?
OK, lets get back to sex.

That has three dimensions.

l=1'
w=1'
h=27'

However, you're right. It's not a cube, because the faces of a cube are all squares of equal size.

*edit--I believe a 1' x 1' x 27' figure would be called a prism.

You're right both times. A 1x1x27 foot object does indeed have three dimensions, and it's not a cube. It would, however, have a cubic volume--as does every three dimensional object, regardless of shape (cement sidewalk slab, bowling ball, gemstone, or whatever.)

let's see... there's two pints in a quart, two hectares in an acre...

See what you started, Jammies. No doubt you've bought 8 cubic yards of topsoil, tilled the garden, and have blooming while all us number crunchers debate the numerical value of infinity plus one.
