Question

The density of lead is 11.4 g/cm3. Convert the density to lb/ft3. 1 lb = 454.55 g 1 ft = 12 in 1 in = 2.54 cm

Answer 1

When we convert 11.4 g/cm³ to lb/ft³, the result obtained is 707.92 lb/ft³

How to convert 11.4 g/cm³ to lb/cm³

454.55 g/cm³ = lb/cm³

Therefore,

11.4 g/cm³ = 11.4 / 454.55

11.4 g/cm³ = 0.025 lb/cm³

How to convert 0.025 lb/cm³ to lb/ft³cm

1 ft = 12 in

1 in = 2.54 cm

Thus,

12 in = 12 × 2.54

12 in = 30.48 cm

We can say

1 ft = 30.48 cm

Therefore,

1 ft³ = 30.48³ = 28316.84 cm³

Now, we can convert 0.025 lb/cm³ to lb/ft³ as follow:

(1/28316.85) lb/cm³ = 1 lb/ft³

0.025 lb/cm³ = 0.025 ÷ (1/28316.85) =  0.025 × 28316.85

0.025 lb/cm³ = 707.92 lb/ft³

Thus,

11.4 g/cm³ = 707.92 lb/ft³
