The wood cube below has a mass of 9grams will it float or sink in water each side 2cms
To determine if the wood cube will float or sink in water, we need to compare its density with the density of water. Density is calculated by dividing the mass of an object by its volume.
The volume of the cube can be calculated by multiplying each side's length, which is given as 2 cm, three times (since it's a cube):
Volume = (2 cm) x (2 cm) x (2 cm) = 8 cm³
Next, we calculate the density of the cube by dividing its mass (9 grams) by its volume (8 cm³):
Density = 9 g / 8 cm³ ≈ 1.125 g/cm³
The density of water is approximately 1 g/cm³. Since the density of the wood cube (1.125 g/cm³) is greater than the density of water (1 g/cm³), the cube will sink in water.
