Answer:
The length of each edge of the base is 7cm.
Step-by-step explanation:
The volume of a prism with square base is given by:

In which l is the length of each edge of the base and h is the height.
A prism with a square base has a height of 15cm and a volume of 735cm3.
This means that 
So





Length is a positive measure. So

Volume in cm³, so the length of each edge is in cm.
The length of each edge of the base is 7cm.
Let x be the number.
Then:
(x)+(x+1)+(x+2)>102
(x)+(x+1)+(x+2)<109
x+x+1+x+2
3x+3>102
3x>102-3
3x>99
x>22
3x+3<109
3x<109-3
3x<106
x<35.33
Therefore, the number can be bigger than 22 but less than 35.333 to meet the requirements.
