how do you get that as the answer
There are 2.54 cm in 1 inch.
There are 453.6 g in 1 lb.
There are 1,728 cubic inches in a cubic foot.
2.70 g/cc x (1 lb/453.6 g) x (2.54 cm/1 inch)^3 x (1,728 in^3/ft^3) =
168.55 lbs/ft^3.
To convert from grams per cubic centimeter (g/cm³) to pounds per cubic foot (lb/ft³), you can use the following steps:
1. Convert grams to pounds:
- There are 453.592 grams in one pound. So, divide the value in grams by 453.592 to get the equivalent value in pounds.
2. Convert cubic centimeters to cubic feet:
- Since there are 2.54 centimeters in one inch, first convert cm³ to in³ by dividing the value in cm³ by 2.54³ (2.54 x 2.54 x 2.54).
- Next, convert in³ to ft³ by dividing the value in in³ by 12³ (12 x 12 x 12) since there are 12 inches in one foot.
3. Combine the results:
- Divide the value in pounds by the value in cubic feet to get the final answer in pounds per cubic foot.
Let's plug in the given value of 2.70 g/cm³ and calculate:
1. Convert grams to pounds:
2.70 g/cm³ ÷ 453.592 g/lb ≈ 0.005946 lb/cm³
2. Convert cubic centimeters to cubic feet:
- Convert cm³ to in³: 0.005946 lb/cm³ ÷ 2.54³ cm³/in³ ≈ 0.0002292 lb/in³
- Convert in³ to ft³: 0.0002292 lb/in³ ÷ 12³ in³/ft³ ≈ 0.0000005237 lb/ft³
So, 2.70 g/cm³ is approximately equal to 0.0000005237 lb/ft³.
