how many liters is 15 gallons? (1 gal = 3.79 l)

Explanation:

Step1: Identify the conversion factor

The conversion factor is 1 gal = 3.79 L.

Step2: Set up the conversion equation

We want to convert 15 gallons to liters. So we multiply 15 by the conversion factor: $15\times3.79$.

Step3: Calculate the result

$15\times3.79 = 56.85$. Rounding to the correct number of significant - figures (since 15 has 2 significant figures, the answer should also have 2 significant figures), the result is 57 L.

Answer:

1. C. Solid
2. 57 L
