Question

The design for a life preserver requires 0.3 kilograms of plastic foam to provide proper buoyancy. What is the volume of the plastic foam required? Rearrange the density formula to isolate V: D = m/V.

Answer 1

To find the volume of the plastic foam required, rearrange the density formula D = m/V to isolate V. Given the mass (m) is 0.3 kilograms, the volume (V) of the plastic foam required depends on the density (D) of the foam.

Step-by-step explanation:

To find the volume of the plastic foam required, we can rearrange the density formula D = m/V to isolate V.
D = m/V
Multiply both sides of the equation by V:
DV = m
Now divide both sides of the equation by D:
V = m/D

Given that the mass (m) of the plastic foam is 0.3 kilograms, we can substitute this value into the formula:
V = 0.3 kg / D

Since the density of the plastic foam is not provided in the question, we cannot calculate the exact volume. The volume (V) of the plastic foam required will depend on the density (D) of the foam.
