Question

How many cubes are missing to build a full cube ?




Please tell me the answer.​

Answer 1

Answer:

45 cubes

Step-by-step explanation:

The guy before me that answered this said 20, he simply filled the empty spaces, after you fill it, it will be a 4 by 5 box which isnt a cube, i added one more layer by multiplying length and width which is 5x5= 25, add it to the 20 cubes and that is 45, hope my explanation isnt confusing
