Final answer:
No, to find the mass of a rectangular object, you need to multiply the object's volume by its density.
Step-by-step explanation:
No, to find the mass of a rectangular object, you need to multiply the object's volume by its density. The formula for volume of a rectangular object is length x width x height. However, to find the mass, you need to multiply the volume by the density, not the length, width, and height.
For example, let's say the length of the rectangular object is 5 cm, the width is 3 cm, and the height is 2 cm. The formula for volume would be 5 cm x 3 cm x 2 cm = 30 cm³. If the density of the object is 2 g/cm³, then you would multiply the volume by the density: 30 cm³ x 2 g/cm³ = 60 g. Therefore, the mass of the rectangular object is 60 g.
