Go out and measure it.
Take the width and length at the bottom.

A cubic yard is 36x36x36

My guess is you can only fill to about 6 inches of the 10.

Roughly 10 trips without the math.
When you have the measurements divide

width times height times depth
into 36x36x36.

Don't assume to can use the whole depth.

Math is our friend...I'm not doubtin' your numbers, just trying my
own. Let me know if I missed something...it's Monday.

As I posted earlier from: http://www.doityourself.com/stry/patiosteps
:

"One cubic yard of ready-mix yields nine contractor-size wheelbarrows
of concrete. "

AFAIK a contractor's wheelbarrow is ~ 6 cu ft and the OP's is
estimated (by him) to be only 2.5 cu ft.

Now, if I do a little math and divide 1 cu yd by 6 cu ft I get

27 / 6 = 4.5 (not nine) which means they are only putting 3 cu ft in
each wheelbarrow - IOW - half full.

Therefore, if the OP puts only 2 cu ft into his 2.25 cu ft
wheelbarrow, it's going to take at least 13.5 loads. If he follows the
lead of the DIY site and only fills his wheelbarrow half way, it's
going to take 18 loads.

Does that sound right?

Maybe, but I didn't do any math.
I looked at the OPs numbers, saw he was just under 36 on the length
1/4 under on the width and 1/6th on the height and that sounded
like about 10. Give or take a few.

Why do math when the OP doesn't have accurate measurements to
start with?

re: Maybe, but I didn't do any math.

I guess there are varying degrees of "doing the math". :-)

Seems to me that you can't "see" that he was fractions under a number
without do some sort of math. If I "see" you get served a steak that
is twice as big as mine, then I did some math just before I called
server over to our table.

You gonna eat that potato?

Snip

Having pushed a wheelbarrow or three hundred as a kid- volume isn't as
important as weight. Wet concrete weighs like a bitch- it would take
superman to push a full-size wheelbarrow of it, especially since we are
usually talking pushing it on dirt or bouncy walkboards. A full one
would usually lose the top 3-4 inches of fill to splashing. If you are
filling the wheelbarrows out of a truck or portable mixer, more
important to have many strong backs and several wheelbarrows staged. You
only have so many minutes of 'open' time before you have to dump the
load Right There, rather than in the forms. Once the concrete shows up,
IT is in charge- no smoke breaks, no lunch, no potty breaks. You move
and shovel and screed till the forms are filled.

Back before concrete pumpers came along, they used to have cute little
self-dumping gas-powered walk-behind 'mules' for use on sites where you
couldn't get the truck close enough.
