Solving Word Problems on Volume of Solid Figures


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?

First let's just find the volume of one book.

Volume is length times width times height.

V = (L)(W)(H)

V = (2.85)(2.15)(0.4)

Just multiply these together in a calculator.

V = 2.451 cubic dm

The volume of one book is 2.451 cubic dm.

Since there are 19 books, just multiply that volume by 19.

2.451*19 = 46.569


Total volume = 46.569 cubic dm.
