Final answer:
To convert the density of Trex from lb/ft^3 to kg/l, you need to multiply by conversion factors. First, convert pounds to kilograms by multiplying by 0.4536. Then, convert cubic feet to liters by multiplying by 28.3168. The density of Trex is 771.15 kg/l.
Step-by-step explanation:
The question is asking for the density of Trex, a manufactured substitute for wood, in kg/l. To convert the density from lb/ft^3 to kg/l, we need to use conversion factors. First, we convert pounds to kilograms by multiplying the density by 0.4536 (since 1 lb = 0.4536 kg). Next, we convert cubic feet to liters by multiplying the density by 28.3168 (since 1 ft^3 = 28.3168 l).
So, the conversion from lb/ft^3 to kg/l is:
- Converting lb to kg: density (in kg/l) = 60.0 lb/ft^3 x 0.4536 kg/lb = 27.216 kg/l
- Converting ft^3 to l: density (in kg/l) = 27.216 kg/l x 28.3168 l/ft^3 = 771.15 kg/l
Therefore, the density of Trex is 771.15 kg/l.
