How large is ukraine compared to the united states.

Answers

Ukraine is about 16 times smaller than United States.

Answer:

United Sates is 16 times bigger than Ukraine.

Explanation:

For finding which one is bigger either Ukraine or USA and by how much,

First:-

Area of landmass of Ukraine is 603,548 km² or 600,000 km² (approx.)

and, Area of landmass of USA is 9,833,517 km² or 10,000,000 km² (approx.)
