Answer:
The cube will float
Explanation:
Before we can decide if the cube will sink or float, we need to calculate the density of the object. We need to know how dense the object is.
Density is defined as the ratio of the mass of an object to its volume. Mathematically,
Density = mass/volume
Given mass = 45g and length of a cube = 6cm
Its volume = length × length × length = 6×6×6 = 216cm³
Density = 45/216
Density of the cube = 0.208g/cm³
The density of the cube is a low value and as such the cube will float
