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.
