# The density of water is 1.00 g/cm^3. What is this density in lb/ft^3?

Dec 11, 2015

The density of water is $\text{62.7 lb/ft"^3}$.

#### Explanation:

Use dimensional analysis.

$\text{1 g = 0.00220462 lb}$

$\text{1 cm"^3=3.53147xx10^(-5) "ft"^3}$

(1.00cancel"g")/(1cancel"cm"^3)xx(1cancel"cm"^3)/(3.53147xx10^(-5)"ft"^3)xx(0.00220462"lb")/(1cancel"g")="62.7 lb/ft"^3"
