The post office does not sell any boxes which have a side length longer than 10 centimeters. I bought a box from the post office that has a volume of 70 cubic centimeters. What could be the dimensions of my box?
You just need 3 numbers that multiply together to give 70
None can be bigger than 10cm
Hint: the factors of 70 (less than or equal to 10) are 1,2,5,7,10
