Question

A student wants to determine the mass of a large plastic cube. The student measures the volume of the cube as

4 cm. The student's teacher states that the density of the cube is 2.0 g/cmº
What is the next step the student should take to find the cube's mass?
O Calculate the mass by dividing volume by density. The result mass will be 2.0 g.
Calculate the mass by subtracting the volume from the density. The resulting mass will be
2.0 g.
Calculate the mass by multiplying volume by density. The resulting mass will be 8.0 g.
Calculate the mass by adding volume and density. The resulting mass will be 6.0 g.

Answer 1

The student should multiply the density of the cube by its volume to find its mass. The correct mass of the cube is 8.0 grams.

Step-by-step explanation:

To determine the mass of an object, one can use the formula where mass is equal to the density multiplied by the volume. In this case, the density of the plastic cube is given as 2.0 g/cm³ and the volume of the cube is measured as 4 cm³. Therefore, to calculate the mass, the student should multiply the density by the volume.

The calculation would be as follows:

Mass = Density × Volume

Mass = 2.0 g/cm³ × 4 cm³

Mass = 8.0 g

Thus, the mass of the cube is 8.0 grams.
