Standing pieces:
2(9x6)+4(9x3) = 108+108 = 216
“L” horizontal pieces:
cut it to 3 squares of 3x3 each
2x3(3x3) = 54
total surface area = 216+54 = 270cm^2

F(x) = 4√(2x³-1)<br> F'(x) =....?

icang [17]

$y= \sqrt[4]{(2x^3-1)} \\ y^4=2x^3-1 \\ 2x^3=y^4+1 \\ x^3= \frac{y^4+1}{2} \\ x= \sqrt[3]{\frac{y^4+1}{2}}$

Therefore, F'(x) = $\sqrt[3]{\frac{y^4+1}{2}}$
