How many for the entire Chinese population?
It sounds like a lot of balls to me.
Wacky Chinese inventor Yang Zongfu has unveiled his answer to Noah’s Ark – a radiation-proof, six ton steel-encased ball designed to protect a family of three from disaster. The bizarre bubble took eccentric businessman Yang two years to build and cost a whopping 1.5 million yuan (£150,868), according to China Daily. The …

Volume approx 30 cubic metres, density therefore 6/30 tons per cubic metre. Yes, it will certainly float (water is 1 ton per cubic metre).
Is it answer A from China Daily "and 1.5 million yuan ($23,400) in creating his safe bubble"

But the Chinese term for Ark (方舟) literally means «square/rectangular boat». Wonder what Eukleides would have said about this attempt to square the circle....
