In the ultrasound test performed in the axial direction on a 75x75x285 mm edge concrete prism weighing 850 g, it was measured that the sound passed through the 285 mm length in 78 microseconds. It was determined that a sample made of the aforementioned concrete made a unit shortening of 7.4x10-4 under 200 kgf/cm2 tension. The f - ε behavior of concrete is represented by the SMITH-YOUNG function. Calculate the possible compressive strength of the concrete in question. (Take the value of e as 2.71.)
