Question

what are the three main base units of the metric system? inches (in), cups, and pounds (lb) inches (in), liters (l), and grams (g) meters (m), centimeters (cm), and megameters (mm) meters (m), liters (l), grams (g)

Explanation:

The metric system has base units for length (meter - m), volume (liter - L), and mass (gram - g). Inches and pounds are imperial units, not metric. Centimeters and megameters are derived from the base - unit of length (meter), not base units themselves.

Answer:

meters (m), Liters (L), grams (g)
