Complete the table by calculating mean t, T, T², and L³.

Step 1: Complete the table by calculating mean t, T, $T^2$, and $L^3$.
The mean time $t$ is calculated as $\frac{t_1 + t_2}{2}$.
The period $T$ is calculated as $\frac{\text{mean t}}{20}$.
$T^2$ is the square of the period.
$L^3$ is the cube of the length L, converted from cm to m ($L(\text{m}) = L(\text{cm})/100$).

Here are the calculations for each row:

• Row 1: $L = 95$ cm
