Help Me Solve This Problem Please...

Each book of a set of encyclopedia measures 2.85dm by 2.15dm by 0.4dm. The encyclopedia has 19 books. What is the total volume of all books?

 

I assume a dm is a decimetre :)

 

V= 2.85*2.15*0.4   * 19

2.85*2.15*0.4*19 = 46.569 dm^3    =   46569 cm^3  =    0.046568m^3
