Final answer:
To find the volume in cubic millimeters, convert the length from centimeters to millimeters and multiply it by the width and height. The volume of the object is 50,000 mm³.
Step-by-step explanation:
To calculate the volume of an object, you need to multiply its length by its width and height. However, these measurements need to be in the same unit. Since we have the width and height in millimeters (mm) and the length in centimeters (cm), we must first convert the length to millimeters. There are 10 millimeters in 1 centimeter, so 5.0 cm is equal to 50.0 mm. Now we can calculate the volume:
Volume = length × width × height
Volume = 50.0 mm × 25.0 mm × 40.0 mm
Volume = 50,000 mm³ (cubic millimeters)
