Acannonball made of iron has a volume of 1115 cm^3. if iron has a density of 7.86g/cm^3, what is the mass in grams of the cannonball? m=v x d

M=V·D

V=1115

D=7.86

M=1115·7.86

M=8763.9

The mass of the cannonball is 8763.9 grams.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
