To find the density of the chocolate bar, we first need to calculate its volume. The formula for the volume of a rectangular prism is:
Volume = Width × Length × Height
Plugging in the given dimensions:
Width = 5.5 cm
Length = 15 cm
Height = 1.5 cm
Now, calculate the volume:
Volume = 5.5 cm × 15 cm × 1.5 cm = 123.75 cm³
Next, we use the formula to find density, which is:
Density = Mass / Volume
Given that the mass of the chocolate bar is 50 g, we can substitute the values:
Density = 50 g / 123.75 cm³
Calculating this gives:
Density ≈ 0.404 g/cm³
Therefore, the density of the chocolate bar is approximately 0.404 g/cm³.
