William's science class staked out plots of soil throughout the school yard. The plots were all the same size, 1 meter X 1 meter square. Each morning, for one week, they counted the earthworms they found in each plot. Once their data had been collected the teacher asked for a reasonable explanation for the count in plot C. Which explanation is the MOST reasonable based on the students data?

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.
