Answer:
Amanda's box volume is 70 cm^3 greater than Mary's
Step-by-step explanation:
Find and then compare the volumes of the two boxes:
Amanda's:  10*10*13.5 cm^3 = 1350 cm^3
Mary's:  8*8*20 = 1280 cm^3
Amanda's box volume is 70 cm^3 greater than Mary's.
 
        
             
        
        
        
3 x 25 =75 and then 5 x 8 =40 and you would just add 75 and 40 which is where you would get 115.  So the answer would be D 25 child 8 adult 
Hope this helps! :)
