1. The problem states that the volume $v$ in the container depends on the number of cubes $x$ according to the equation: $$v = 8 + 4x$$ 2. We are asked to find the volume when there are 6 cubes in the container, i.e., when $x = 6$. 3. Substitute $x = 6$ into the equation: $$v = 8 + 4(6)$$ 4. Calculate the multiplication: $$v = 8 + 24$$ 5. Add the numbers: $$v = 32$$ 6. Therefore, the volume in the container when there are 6 cubes is 32 milliliters.
