Question
A cube has a side of 3 cm. It has a mass of 300 grams. The density of the cube isSelect one:a.11.1 g/cm3 and will sink in waterb.100 g/cm3 and will float in waterc.100 g/cm3 and will sink in waterd.33.3 g/cm3 and will sink in watere.11.1 g/cm3 and will float in waterf.33.3 g/cm3 and will float in water
Solution
To find the density of the cube, we need to use the formula for density, which is mass/volume.
Step 1: Find the volume of the cube. The formula for the volume of a cube is side^3. So, the volume of the cube is 3 cm * 3 cm * 3 cm = 27 cm^3.
Step 2: Find the density of the cube. The formula for density is mass/volume. So, the density of the cube is 300 g / 27 cm^3 = 11.1 g/cm^3.
Step 3: Determine if the cube will sink or float in water. The density of water is 1 g/cm^3. If the density of the object is greater than the density of water, it will sink. If it's less, it will float. Since 11.1 g/cm^3 is greater than 1 g/cm^3, the cube will sink in water.
So, the answer is a. 11.1 g/cm^3 and will sink in water.
