Jess made 3 different stacks of wooden blocks. The first stack was 8 blocks high, the second stack was 4 blocks higher than the first, and the final was 8 blocks higher than the second. in total, how many blocks did jess use for all 3 stacks

Jess used 40 blocks in total.

Step-by-step explanation:

First stack: 8 blocks

Second stack: First stack + 4 = 8 + 4 = 12 blocks

Third stack: Second stack + 8 = 12 + 8 = 20 blocks

Total number of blocks: First stack + Second stack + Third stack = 8 + 12 + 20 = 40 blocks
