Answer:
A) 6 [g/cm^3]
Step-by-step explanation:
The volume of a cube is equal to the product of height by width by length, all these dimensions are equal.
V = L*L*L
where:
L = 5 [cm]
V = (5)^3
V = 125 [cm^3]
Density is defined as the relationship between mass and volume.
density = mass/volume
density = 750/125
density = 6 [g/cm^3]
