In the four corners of a square with side length of ACM, subtract one square with side length of 5cm, (2 / a > 5) In the four corners of a square with side length of ACM, subtract a square with side length of 5cm, (2 / a > 5) to make a 900 cubic centimeter uncovered box. How much is the side length a of the square?
900 = (A-10) square * 5
(A-10) square = 180
A-10=13.416
A=23.416
There is a rectangular piece of white iron, 126 cm long and 288 cm wide. If you want to cut it into the largest square with equal area, how many pieces can you cut into?
The greatest common factor of 126 and 288 is 18
126/18×288/18
=7×16
=102 yuan
