Final answer:
The volume of the sheet requires the sheet's thickness or the density of the material, which are not provided. We can only calculate the area of 432.0 cm² based on the provided dimensions. For complete volume calculation, additional information is necessary.
Step-by-step explanation:
To calculate the volume of the sheet of substance B, we first use the measurements given for the sheet, which are 24.0 cm by 18.0 cm. The volume of a sheet is found by multiplying its area by its thickness. However, we do not have the thickness in this question, which is required to calculate the volume. To find the thickness, we would need additional information, such as the density of the substance and the mass of the sheet. Since only the area calculation seems relevant to the question, we can calculate the area as follows:
Area = length × width
Area = 24.0 cm × 18.0 cm = 432.0 cm²
With the area known, and assuming a uniform thickness, we could use the mass of the sheet (6.50 g) along with the density of substance B (if provided) to calculate the volume. The formula to calculate volume using mass and density is:Volume = mass / density
However, without the density or thickness, we can't proceed to calculate the volume. In problems such as the one given for aluminum foil, we can use the surface density (mass per unit area) to find the mass or volume if the thickness is known.
