deep
Tension
one is in the reef and the other isn't, it is in dirt.
Depends on how deep you want to fill it...
8m3
There is no dirt in the hole, but if you want to know how much dirt was removed to create the hole, then:3 acres is an amount of area (you don't have 'square acres'). You could express this volume as acre-feet, but this term is usually used when referring to flooding (an acre of land flooded with 1 foot of water, for example). 1 acre = 43560 square feet, so 3 acres = 130680 square feet.(130680 square feet)*(200 feet) = 26136000 cubic feet {26.136 million cubic feet} In the dirt industry, the standard measurement is cubic yards {often referred to as just 'yards' of dirt}. There are 27 cubic feet in a cubic yard, so this is equivalent to 968000 cubic yards.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
All of it
None. If it is a hole that means there is absolutely nothing inside the hole meaning that there is no dirt at all in a hole even if it was dug up from dirt. No matter how big the hole, the result is the same.
None, if it is a hole.
I'm assuming you mean one meter deep with a one square meter footprint. The answer is 1*1*1=1m^3 = one cubic meter. Actually, that is how much dirt was taken out to make the hole. There should be no dirt in the hole, otherwise it wouldn't be a hole.
deep
You need to tell us how DEEP.
600lb.
6 cubic square
6 cubic yards of dirt will cover 70 sq ft ... 2 ft 3 3/4 inches deep
16 sq ft*0.5 ft = 8 cubic feet.
