24 inches is i am not mistaking
6 to 12 is +6
12 to 18 is +6
so 18 to 24 is +6
The exponent for that would be 13^3.
If the answer is incorrect, then i am sorry.
2+x=50
That is what I would do. I hope this helps!
Volume of the cube with side 4p = 4p x 4p x 4p = 64p³
Volume of the cube with side 2q² = 2q² x 2q² x 2q² = 8q⁶
Total Volume = 64p³ + 8q⁶
Total Volume = (4p)³ + (2q²)³
Total Volume = (4p + 2q²)( ( 4p)² - (4p)(2q²) + (2q²)²)
Total Volume = (4p + 2q²)( 16p² - 8pq² + 4q⁴)
Answer: (4p + 2q²)( 16p² - 8pq² + 4q⁴)
