Answer:
64[tex]x^{6}[/tex] + 144[tex]x^{4}[/tex] + 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[tex]x^{4}[/tex] + 24x² + 9)(4x² + 3) ← distribute by 4x² and 3
= 64[tex]x^{6}[/tex] +96[tex]x^{4}[/tex] + 36x² + 48[tex]x^{4}[/tex] + 72x² + 27 ← collect like terms
= 64[tex]x^{6}[/tex] + 144[tex]x^{4}[/tex] + 108x² + 27
