Word Problem of the Week

Oct 12, 2017

  Hey math fans! This week’s word problem challenge will be a lot of fun for all you visual problem solvers, and great math skills practice for ALL of our upper elementary mathletes out there. Take a look at the challenge below and give it a try. 

Question: Alli has a box that is exactly the right size to hold 7 layers of 9 rows of 11 cube-shaped erasers. How many erasers fit inside the box?

Take your time figuring it out. When you're ready, check your solution against ours below.

Solution: The length of the box is equal to 11 erasers, the width is equal to 9 erasers, and the depth is equal to 7 erasers. So, the box will hold 11 × 9 × 7 = 693 erasers in total
