Don’t mind the thing at the top but i really need help.

vol formula is l×w×h

4×4×4=64cm³

V = 64 cm^3

d = 0.25 g/cm^3

Explanation:

Volume = length * width * height

so, V = 4 cm * 4 cm * 4 cm

V = 64 cm^3

density = mass/volume

d = 16 g / 64 cm^3

d = 0.25 g/cm^3

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
