MATTHEW USA: (70°F − 32) × 5/9 = 21.111°C

MARLIJIN NETHERLANDS: (70K − 273.15) × 9/5 + 32 = -333.7°F

MAHDI KENYA: (70°C × 9/5) + 32 = 158°F

(i put the formula on so its easier just search up which is coldest and explain, your welcome :)

Yes.

Explanation:

Matthew (USA): (70°F − 32) × 5/9 = 21.111°C

Marlijin (Netherlands/UK): (70K − 273.15) × 9/5 + 32 = -333.7°F

Mahdi (Kenya/Africa or something) : (70°C × 9/5) + 32 = 158°F

the answer is D) Titanium. you divide the mass by volume and titanium has the closest density yo the number you get. I also chose titanium and got it right. goodluck
