The total volume is 1 cubic decimeter and the area is 1 square meter The total volume of the craftwork is 1 cubic decimeter, which is made of the alloy material with the density of 8,0 × 10 cubic kg cubic meter. The area is 1 square meter, and the contact area of the swallow on the horizontal table is 20 square meters. What is the quality of the craftwork
The mass is only related to density and volume, but not to contact area
8.0×10^3×1×10^(-3)=8(kg)
