It depends on the scale of that particular map.
64 mm squared. (8mm multiplied by 8mm)
It is: 886 = 384 square mm
The surface area of a cube can be calculated by finding the area of each of the cube's six square faces and adding them together. Since all sides of a cube are equal, the area of one face is the side length squared. Therefore, the surface area of a cube with a side length of 8mm is 6 times 8mm squared, which equals 384 square millimeters.
It is: 0.5*6*8 = 24 square mm
6 faces, each of 8mm*8mm = 6*64mm2 = 384 mm2
8mm square
its 8mm square
Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.
Your jeweler is better equipped to help you figure out the answer to your question. With a round mounting and a square diamond, your question reads like you're trying to drive a square peg into a round hole.
