Heavier 4553

What is the mass of a cube of cast iron with an edge length of 2.3 dm if we know that the mass of 1 dm³ of cast iron is 7.3 kg? Will the same size cube of cork be heavier if we know that the weight of 1 m³ of cork is 250 kg?

Correct answer:

m1 =  88.8191 kg
m2 =  3.0418 kg

Step-by-step explanation:

a=2.3 V=a3=2.33=12.167 m1=7.3 V=7.3 12.167=88.8191 kg
m2=250/1000 V=250/1000 12.1673.0418 kg m1>m2
