Answer: 144
Explanation:
since the shorter side is 2 cubed inches, the opposite side is the same length. same thing with the longer side, it’s 4 cubed inches, which the opposite side is the same length
so if you take 2 cubed and add it with 2 cubed, you will get 16.
then you take 4 cubed and add it with 4 cubed, and you get 128.
and then finally, you want to add those 2 answers together: so 16 plus 128.
you will get your final answer, which is 144.
