How do you get the answer of 3million sq feet to sq meters?

Answer 1

1 ft = 0.3048 m (exactly)

⇒ 1 sq ft = 1 ft x 1 ft

= 0.3048 m x 0.3048 m

= 0.09290304 sq m (exactly)

To convert square feet to square metres multiply by that:

⇒ 3 million sq ft = 3 000 000 x 0.09290304 sq m

≈ 278 710 sq ft.
