To solve for $t$ in the equation $D(h^3 + n) = t$, we need to isolate $t$ on one side. Here's the step-by-step process:

Step 1: Start with the given equation:

$D(h^3 + n) = t$

Step 2: Identify that the right-hand side already equals $t$:

$t = D(h^3 + n)$

Thus, $t$ is already expressed in terms of $D$, $h$, and $n$. No further manipulation is necessary.

The solution is: $t = D(h^3 + n)$
