This was found by calculating the total volume of the dog box ($117\text{ cm} \times 97\text{ cm} \times 61\text{ cm} = 692{,}289\text{ cm}^3$) and subtracting the combined volume of the three dog compartments ($3 \times 169{,}556\text{ cm}^3 = 508{,}668\text{ cm}^3$). { "subject": "Mathematics", "question_type": "Multi-part", "knowledge_point": [ "Mathematics", "Geometry", "Volume of Rectangular Prism" ] }
