Good afternoon my question is I wanted to know how many meters of sand and stone and how many bags of cement I need to make an earthenware of 35 meters by 15 cm high by approx

Hi. They are 35 m²? Keep in mind that for m³ of concrete, you use 6 bags of cement, 0.75 m² of coarse sand and 0.40 m³ of broken stone or boulder. If they were 35 m² x 0.15 m high, it would be a little more than 5 m³ of concrete. regards
