Verified answer

(3 m^2)(10 000 cm^2/1 m^2) = 30 000 m^2

(300 m/seg)( 1 km/1000 m)(3600 seg/1 h) = 1080 km/h

(300 m^3/seg)(0.02933 pie^3/1 m^3)(3600 seg/1 h) = 31 676.4 pie^3/h

(3*10^5 km/seg)(1000 m/1 km) = 3x10^8 m/seg

(4 kg/min)(2.2046 lb/1kg)(1 min/ 60 seg) = 0.147 lb/seg

= 30 000 cm2

= 1 080 km/h

= 3.8 x 10 a la 7 ft3/h

= 3 x 10 a la 8 m/s

= 528.6 lb/s

3m al cuadrado a cm al cuadrado=900

300m/s a km/h =ke flojera

3x10ala 5 km/s a m/s

4kg/min a ib/s

3m al cuadrado a cm al cuadrado = 3m^2 ----> cm^2

c = centi = 0.01 ------> 1 cm = 0.01 m

3m^2 * ( 1 cm / 0.01 m)^2 = 30,000 cm^2

300m/s a km/h

1 Km = 1000 m y 1 h = 3600 s

300 m/s (1 Km / 1000 m) * (3600 s/ 1 h) = 1080 Km / h

------------------------------------------------------------------------------------------------------------------------------

300mcubicos/s a pie cubico/h -----> 300 m^3/s ---> pies^3/h

1 m = 3.2808399 pies ; 1 h = 3600 s

300 m^3/s * ( 3.2808399 pies / 1 m)^3 * (3600 s / 1 h) = 38139840 pies^3/h

--------------------------------------------------------------------------------------------------------------------------------

3x10ala 5 km/s a m/s ------> 3 x 10^5 km/s ----> m/s

1 Km = 1000 m

3 x 10^5 km/s * {1000 m / 1 Km ) = 3 x 10^8 m/s = 300000000 m/s

4kg/min a ib/s

1X 0.45359 lb = 1 kg, 1 min = 60 seg

4 kg/min * (1X 0.45359 lb / 1 kg) * ( 1 min / 60 seg) = 0.030239 lb / s ; (lb avor)
