Question

元/t换算成元/m2,求救!长宽高1000mm*400mm*75mm的花岗岩石板,3000元/t,花岗岩密度2.61g/

Answer 1

花岗岩密度2.61g/cm3=2.61x0.001x0.001t/(0.01x0.01x0.01m^3)=2.61t/m^3;

长宽高1000mm*400mm*75mm=1m*0.4m*0.075m;

1块石板的体积=1*0.4*0.075=0.03(m^3),面积=1*0.4=0.4（m^2）;

质量=2.61x0.03=0.0783（t）,

价格=3000*0.0783=234.9（元）;

（每平方米）单价=234.9元/(0.4m^2)=587.25（元/m^2）
