The project is to remove some hillside to expand the property. It is 50 foot long and he wants to dig back 10 feet. The height is about 5ft.

What is the formula to figure this out? Thanks

5H X 10D / 2 = 25 sq.ft. The Area of a triangle

25sq.ft x 50 feet long = 1250 cu.ft. Amount of soil to remove.

22 Yards per dump truck (This can vary, just an example)

27 cu.ft. = 1 cu.yd.

1250 / 27 = 46 loads (this represents compacted soil)

I would say your an easy 50 truck loads.

Nope, I've calcuated rock and gabion baskets for creek bank restorations because that's what I usualy deal with. Never have had to load dirt out into a dump truck. First for everything.

I'm not good at math, at all. Once I'm shown how to do it though I get the hang of it.

I'm glad you don't estimate for me I came up with about 46 yards figure swell depending on dirt I would say 50 to 55 yards at about 12 to 14 yards per truck 5 loads at the most

haha, your right....whiskey and Math don't mix. That was supposed to be 46 yards not 46 trucks, haha.I'm glad you don't estimate for me I came up with about 46 yards figure swell depending on dirt I would say 50 to 55 yards at about 12 to 14 yards per truck 5 loads at the most

Yea so 46 yards is like 3 trucks more likely.

Yeah.. after thinking about it I only see about 5-6 truckloads there because the hill gets steeper and the height increases as it goes back.haha, your right....whiskey and Math don't mix. That was supposed to be 46 yards not 46 trucks, haha.

Guys, its tuesday. Hitting the sauce a little early arent we?

length x width x height = cubic feet

cubic feet divided by 27 = yards

Thats 92 yards. Dont know how your getting 46
