Explicație pas cu pas:

a) 2,75 m cubi + 34 dm cubi = 2,75m cubi + 0,034 dm cubi = 2,784 m cubi

b) 85,4 dam cubi - 480 000 dm cubi = 85400m cubi - 480 m cubi = 84920 m cubi

c) 3,5 cm cubi + 85 mm cubi +0,002 dm cubi = 0,0035dm cubi + 0,000085 dm cubi + 0,002 dm cubi = 0,005585 dm cubi

d) 2 700 dam cubi +4,8 m cubi+ 300 dm cubi = 2700000 m cubi + 4,8 m cubi + 0,3 m cubi = 2700005,1 m cubi

e) 7 km cubi +0,004 hm cubi + 335 000 dam cubi =7000000 dam cubi + 4dam cubi + 335000 dam cubi = 7335004 dam cubi
