Question

Bob used identical cubes to build a rectangular tower that is 25 cubes tall, 5 cubes wide, and 6 cubes long. Beatrice used the same type of cube to build a tower that is 12 cubes tall, 3 cubes wide, and 5 cubes long. Then Bob destroyed Beatrice's tower and used all of her cubes to make his tower even taller, while keeping its width and length the same. How many cubes tall is Bob's tower now?

HEELLLLLPPPP :(

Answer 1

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!!!
