Answer: 8.1 g/cm
Explanation:
Density is equal to mass divided by volume. You are given a mass of
64.7
grams. You can find the volume of the cube by doing height multiplied by width multiplied by the depth.
Because all of the sides of a cube are the same length, the volume just ends up being
(2 cm) = 8 cm
Now plug both of those numbers into your density equation
p= m/v = 64.7 g/8 cm = 8.1 g/cm
