A hollow iron cube has measures 5cm on each side and has a mass of 20g will the iron cube sink or float?
To determine whether the hollow iron cube will sink or float, we need to compare the density of the cube with the density of the liquid it will be placed in.
Density is defined as mass per unit volume. In order for an object to float, its density must be less than the density of the liquid it is immersed in. If the object has a greater density than the liquid, it will sink.
To calculate the density of the iron cube, we need to know its volume. The volume of a cube can be calculated by cubing its side length.
Given:
Side length of the iron cube = 5 cm
Mass of the iron cube = 20 g
First, let's find the volume of the cube:
Volume = (Side length)^3 = 5 cm * 5 cm * 5 cm = 125 cm^3
Next, let's calculate the density of the iron cube:
Density = Mass / Volume = 20 g / 125 cm^3
Now, we need to compare the density of the iron cube with the density of the liquid it will be placed in. If the density of the cube is less than the density of the liquid, it will float; otherwise, it will sink.
Since we don't know the density of the liquid, we cannot conclusively determine whether the iron cube will sink or float.
