27.6 m = 276 dm = 2760 cm = 2.76 dam

38 dam = 3.8 hm =0.38 km =380 m

2)

$36.12 m^2 = 3612 dm^2 = 0.3612 dam^2$

$1.567 hm^2 = 156.7 dam^2= 15670 m^2$

3)

$6.2579 m^3=6257.9 dm^3 = 6257900 cm^3$

$957698 mm^3= 0.000957698 m^3 = 0.957698 dm^3$

$3.25 hm^3=3250 dam^3 = 3250000 m^3$

4)

$S_l=4*l^2=4*70^2=19600 cm^2$

$S_t=6*l^2=6*70^2=29400 cm^2$

5)

$S_l=perimetro_{base}*altezza=2(80+40)*50=12000 cm^2$

$S_t=S_l+2Area_{base}=12000 + 2*80*40= 18400 cm^2$
