Question

1. How many m2 (meters squared) are in 906,633,355 in2 (inches squared) given that 1in = 2.54 cm (exactly) and 12 in =1ft.
   

Answer 1

906,633,355 in2 :

1 inch = 2.54 cm

906,633,355 = 906,633,355 x (2.54 cm)^2

                      = 5.85 x 10^9 cm2

1 cm2 = 0.0001 m2

5.85 x 10^9 cm2 = 5.85 x 10^9 x 0.0001

                             = 584923.4 m2

                             = 5.85 x 10^5 m2
