Question

If feathers have a density of 0.500 lbs/ft^3, what volume in ft^3 will 8.0 lbs of feathers occupy?

Answer 1

Answer:

The volume of the feathers in ft³ = 16 ft³

Explanation:

Density: This can be defined as the ratio of mass of a body to the corresponding volume of that body. The S.I unit of Density is kg/m³

Mathematically it can be expressed as,

D = m/v ................................... Equation 1

making v the subject of the equation above,

v = m/D ............................. Equation 2

Where D = Density of the feathers, m = mass of the feathers, v = volume of the feathers.

Given: D = 0.50 lbs/ft³, m = 8.0 lbs.

Substituting into equation 2

v = 8/0.5

v = 16 ft³

Thus the volume of the feathers in ft³ = 16 ft³
