A rectangular container has inside dimensions of 8 cm×5 cm×3 cm8\text{ cm} \times 5\text{ cm} \times 3\text{ cm}8 cm×5 cm×3 cm. It has a mass of 50 g when empty and a total mass of 290 g when completely filled with a liquid. Which expression represents the density of the liquid in g/cm3\text{g/cm}^3g/cm3?
2908×5×3\frac{290}{8 \times 5 \times 3}8×5×3290
290−508×5×3\frac{290 - 50}{8 \times 5 \times 3}8×5×3290−50
8×5×3290\frac{8 \times 5 \times 3}{290}2908×5×3
8×5×3290−50\frac{8 \times 5 \times 3}{290 - 50}290−508×5×3
