Answer:
21 boxes of books
Step-by-step explanation:
guy= 140 lbs
each box= 40lbs elevator can only weigh up to 1010
i took 1010- 140 and got 870lbs left for the books
then i took 870 divided by 40 (to see how many boxes of books can be put on the elevator) and got 21.75
so 21 boxes could go on the elevator at a time
The formula is base x height = volume so 6 x 4 = 24
