Answer:
ok so first we have to find out how meaning cubes are in each tower so
bob 25*5*6=750
beatrice 12*3*5=180
ok so we want to see how many extra layers bob can add on with beatrices blockes so from looking at bobs tower we can see that 5*6 each layer is 30 so
180/30=6
so bobs will be 31 blocks tall
Hope This Helps!!!
