Integration — practice question

The diagram depicts the curve $y = \frac{x^2}{1 + x^3}$ for $x \ge 0$, together with its maximum point $M$. The shaded region $R$ lies between the curve, the $x$-axis and the lines $x = 1$ and $x = p$.
(i)[4]

Find the exact $x$-coordinate of $M$.

(ii)[6]

Calculate the value of $p$ for which the area of $R$ is equal to $1$. Give your answer correct to $3$ significant figures.
