write an expression to show the total volume of the two boxes i-ready

Answer:
The answer is 512 in³.
Step-by-step explanation:
The formula for the volume of the box is V = s³.
Since 8 is the side length, substitute s for 8 in the formula: V = 8³.
8³ is the same as 8×8×8, which is equal to 512.
Therefore, the answer is 512 in³.
