Final answer:
To find the volume of the object, multiply its length, width, and height. The volume is 50,000 mm³.
Step-by-step explanation:
To find the volume of an object, we multiply its length, width, and height. In this case, the length is given as 5.0 cm, the width is given as 25.0 mm, and the height is given as 40.0 mm. We need to convert the width and height to cm to match the unit of length. Since 1 cm is equal to 10 mm, the width is 2.5 cm (25.0 mm ÷ 10) and the height is 4.0 cm (40.0 mm ÷ 10). Now we can calculate the volume by multiplying the length, width, and height in cm: volume = 5.0 cm × 2.5 cm × 4.0 cm = 50.0 cm³. However, the question asks for the volume in mm³, so we need to convert the volume to mm³. Since 1 cm³ is equal to 1,000 mm³, the volume in mm³ is 50,000 mm³.
