Explicație pas cu pas:
164m= 1640 dm ( 1 m = 10 dm )
66,4m patrati=6640 dm patrati ( 1 m patrat = 100 dm patrati )
46,4dm cubi=0,0464 m cubi ( 1 m cub = 1000 dm cubi )
46,4 : 1000 = 0,0464
29,6m=2960 cm ( 1 m = 100 cm )
39,6m patrati=3960 dm patrati ( 1 m patrat = 100 dm patrati )
19,6m cubi=19600 dm cubi ( 1 m cub = 1000 dm cubi )
19,6 x 1000 = 19600
