How many squares can be cut by WEDM 1 hour?

The efficiency of wire cutting can be measured by the area cut per unit time. Assuming that the efficiency of WEDM is E mm2/min, the area (a) that WEDM can cut in 1 hour can be calculated by multiplying e by 60, because 1 hour is equal to 60 minutes. A=E×60. According to the requirements of the topic, calculate the area that WEDM can cut in 1 hour, and substitute E into the formula for calculation. According to the given information, it is impossible to determine the specific WEDM efficiency E and get accurate results. However, in the explanation, an assumption is used, that is, the efficiency of wire cutting is e mm2/min. According to this assumption, the calculation result is that 1 hour can cut 60000 square millimeters.
