The side length, sofa cube is 4x^2+3. If V=s^3
what is the volume of the cube?

64 + 144 + 108x² + 27

Step-by-step explanation:

Using the formula for volume, V = s³, then

V = (4x² + 3)³

This may be expanded as

(4x² + 3)(4x² + 3)(4x² + 3) ← expand the first 2 factors using FOIL

= (16 + 24x² + 9)(4x² + 3) ← distribute by 4x² and 3

= 64 +96 + 36x² + 48 + 72x² + 27 ← collect like terms

= 64 + 144 + 108x² + 27

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
