V = volume of a cylinder = Pi*Diameter*depth
144 square inches = 1 square foot
volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet
We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.

How many Cubic feet in 30 holes 5 inches deep and 10 in diameter?
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.

What are the ring sizes and how are they measured?
"Ring" refers to the diameter of the cigar. It's in 1/64ths of an inch, so a 32 Ring cigar is 32/64" in diameter, or one-half inch. A 48 Ring cigar is 3/4" in diameter, and so on. Apparently there's a ring gauge you can get to measure cigars; it would have holes in it in various sizes, and whichever hole the cigar fits snugly into is the cigar's ring size. You could also use a ruler, calipers, just whatever you wanted.You might see a cigar specified as 6-1/2" x 42 ring. This cigar would be six and a half inches long by 42/64"in diameter. (The name for this size is Lonsdale.)Box-pressed cigars also have ring sizes, although those cigars are square--a 48 Ring box-pressed cigar is 3/4" x 3/4".

You want to drill three equadistant holes in a circle three inches in diameter?
simple option: take a string, wrap it around the tube, cut off extra, measure the string. Divide by 3, use a ruler to mark the 3 spots on the string, wrap back around tube, and transfer the dots to the tube. DRILL! Accurate option: find circumference of tube. (you can find this by measuring the diameter of the tube, multiply that by PI) divide by 3, mark a starting point, drill holes offset by your length.
Are there black holes the size of stars?
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
