Question

Passe 8.749,2 mm quadrados para km quadrados

Answer 1

1 m = 1.000 mm
1 m = 1*10^3 mm

1 km = 1.000 m
1 km = 1*10^3 m

1 km = 1.000*1.000 mm
1 km = 1.000.000 mm
1 km = (1*10^3) * (1*10^3) mm
1 km = 1*10^6 mm

1 km^2 = (1.000.000 mm)^2
1 km^2 = 1.000.000.000.000 mm^2
1 km^2 = 1*10^12 mm^2

1 km^2 ------ 1*10^12 mm^2
x -------------- 8.749,2 mm^2

x = 1 km^2 * 8.749,2 mm^2 / 1*10^12 mm^2

x = 8,7492*10^3 km^2 / 1*10^12

x = 8,7492*10^(3-12) km^2

x = 8,7492*10^-9 km^2

x = 0,0000000087492 km^2
