Calculate the density, mass and weight of an object if it occupies 200 ft^3 and has a specific volume of 10 ft^3 /lb.

a) 0.1 lb/ft³

b) 20 lb

c) 88.788 N

Explanation:

Given:

Volume of the object = 200 ft³

Specific volume = 10 ft³/ lb

Now,

Density =

or

Density = = 0.1 lb/ft³

also,

Specific volume =

or

10 =

or

Mass = 20 lb

And,

Weight =  Mass in kg × Acceleration due to gravity

Mass = 20 lb

and 1 lb = 0.453 kg

thus,

20 lb = 20 × 0.453 = 9.06 kg

Therefore,

weight = 9.06 × 9.8 = 88.788 N

the answer would be   dignified - apex
