Hi,

We believe there may be an error on the solution page for Worksheet 141-1.

Question 4 asks how many cubic dm will fit in a box that measures 2 m by 1.1 m by 40 cm. The answer given is: V = 20 x 11 x .4 = 88 dm cubed. I think the .4 should be 4.

And therefore, if 40 cm = 4 dm, then the answer would be 880 dm cubed.

Hello Julia (Liam's mom),

You are correct. We will update the Solutions and the Correction page. Thanks so much.
