Marcus stacked 2
harkovskaia [24]

Answer:

2 feet

Step-by-step explanation:

Since each piece of wood is 2/3 of a foot tall, and there are two pieces of wood stacked on top of each other, you need to add 2/3 twice to get the total height of the pile.

2/3 + 2/3 = 6/3

6/3 = 2

Therefore, the pile is 2 feet tall.
