First determine the number of square feet of the puddle. 20' x 20' = 400 square feet. Since the puddle is 1" deep, (I'm assuming the puddle is one inch even though there isn't any indication of whether the numeral one is an inch, or a foot. It's a puddle, after all.), we'll convert the 400 sq. ft. to square inches. 400 sq. ft. X 144 = 57,600 (There are 144 sq. inches in a sq. Foot) This give us the value in cubic inches. Next convert the entire number of cubic inches into cubic feet, it's a nice small number to deal with. There are 1728 cubic inches in a cubic foot so we'll divide the number 57,600 (cu. inches) by 1728 (cu. inches) to give us 33.333 cubic feet. Now multiply the number of cubic feet (33.333) times the weight of a cubic foot of water, which happens to be 62.4 lbs. (Water treatment field study, second edition) 33.333 X 62.4 = 2079.999 lbs. (Rounded off to 2080 lbs.) If the question was for a puddle 1 ft. deep the solution is even easier. Simply multiply the sides to obtain the square footage. Since the puddle is 1 foot deep the area, (square footage), of the puddle will be the same as the cubic volume, or 400 cubic feet. Now multiply that number times the weight of a cubic foot of water. 400 cu. ft. X 62.4 lbs/cu. ft. = 24,960 pounds.
The density of limestone varies from something on the order of 110 pounds per cubic foot (a shade over 1 ounce per cubic inch) to over 160 pounds per cubic foot (about 1.5 ounces per cubic inch).
5 litres is 305 cubic inches.

Take away 4. 64 remain. 64 = 43 Make four layers of (4x4) blocks in each layer to construct a (4x4x4) cube with 64 blocks.
There are NO blocks in cubic feet.
It would be equal to the number of blocks in cubic inches.

You need 8 cubic blocks of sides 0.5 inches to make a 1 inch block.
Volume of 1 inch block is 1 cubic inch Volume of 1/2 inch block is (1/2) x (1/2) x (1/2) = 1/8 cubic inch Therefore number of 1/2 inch blocks in 1 cubic inch block = 1/(1/8) = 8

The number of scaffolding pipes required would depend on the dimensions of each pipe and the design of the scaffolding structure. To calculate the exact number of pipes needed to construct 1000 cubic meters of scaffolding, you would need to know the length, width, and height of the scaffolding, as well as the spacing and configuration of the pipes.
A block is one cubic metre, one kilometre is 1,000 blocks long.
If you want to know the volume of blockfill for 8 inch blocks its 120 blocks to the cubic metre of concrete
1 Block is a cubic metre, so 1km is 1,000 blocks.
