Answer:
6,000
Step-by-step explanation:
To find the volume, you have to solve the width x length x height.
So, 1 of the containers is 20(W) x 15(L) x 10(H) which equals to a volume of 3,000.Then we have another container with the same dimensions. That means we will add 3,000 because it's the same. 3,000 + 3,000 = 6,000
Hope this helped :)
