Question

)) Irene made 4 stacks of wooden blocks. The first stack was 4 blocks tall. The second

stack was 7 blocks taller than the first. The third stack was 9 blocks shorter than the second
stack, and the last stack was 3 blocks taller than the third stack. How many blocks did Irene
use in all?​

Answer 1

Explanation:

If we know the first set of them is 4 blocks tall and the second set is 7 blocks taller.we add 4 plus 7=11 then the third set was 9 blocks shorter so we take away 11-9=2 and then last stack was 3 blocks taller which 2+3=5 so then u add all the answers up like this 4+11+2+5=22 the answer is 22 hope that help.!

Answer 2

I am pretty sure the answer is 30 blocks :)

4 + 11 + 6 + 9 = 30 blocks
