Why do you call a large rock orbiting the sun a asteroid?

The term "asteroid" has come to mean any small, rocky object in orbit around the Sun. The orbits between Mars and Jupiter contain lots of asteroids because there's not a planet there to clear that zone. ... Thus Ceres has been "promoted" to a dwarf planet.Jun 6, 2016

Explanation:

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
