Examples
Example 1
Convert $25.0\ \text{cup (us)}$ to $\text{ft³}$.
$$\text{Volume}_{\text{ft³}} = 25.0 \cdot 0.008355034722222222222222222222222222$$
$$\text{Volume}_{\text{ft³}} = 0.208876$$
$$\therefore \ 25.0\ \text{cup (us)} = 0.208876 \ \text{ft³}$$
Example 2
Convert $60.0\ \text{cup (us)}$ to $\text{ft³}$.
$$\text{Volume}_{\text{ft³}} = 60.0 \cdot 0.008355034722222222222222222222222222$$
$$\text{Volume}_{\text{ft³}} = 0.501302$$

Example 3
Convert $100.0\ \text{cup (us)}$ to $\text{ft³}$.
$$\text{Volume}_{\text{ft³}} = 100.0 \cdot 0.008355034722222222222222222222222222$$
$$\text{Volume}_{\text{ft³}} = 0.835503$$
$$\therefore \ 100.0\ \text{cup (us)} = 0.835503 \ \text{ft³}$$
Example 4
Convert $130.0\ \text{cup (us)}$ to $\text{ft³}$.
$$\text{Volume}_{\text{ft³}} = 130.0 \cdot 0.008355034722222222222222222222222222$$
$$\text{Volume}_{\text{ft³}} = 1.086155$$
$$\therefore \ 130.0\ \text{cup (us)} = 1.086155 \ \text{ft³}$$
Example 5
Convert $160.0\ \text{cup (us)}$ to $\text{ft³}$.
$$\text{Volume}_{\text{ft³}} = 160.0 \cdot 0.008355034722222222222222222222222222$$
$$\text{Volume}_{\text{ft³}} = 1.336806$$
$$\therefore \ 160.0\ \text{cup (us)} = 1.336806 \ \text{ft³}$$
