Final answer:
5 m 18 cm equals 5180 mm, and 56 cm 8 mm equals 568 mm. This is done by first converting meters and centimeters to centimeters and then converting the total centimeters to millimeters by multiplying by 10.
Step-by-step explanation:
To convert 5 m 18 cm to millimeters, first add up all the centimeters. There are 100 cm in 1 m, so 5 m equals 500 cm. Add the 18 cm, and you have a total of 518 cm. Then, to find millimeters, remember that there are 10 mm in 1 cm, so you multiply 518 cm by 10 mm/cm:
518 cm × 10 mm/cm = 5180 mm
For converting 56 cm 8 mm to millimeters, you have a simpler task since only the 8 mm needs to be added to the centimeters after converting them to millimeters:
56 cm × 10 mm/cm = 560 mm
Now add the 8 mm:
560 mm + 8 mm = 568 mm
So, 5 m 18 cm is equal to 5180 mm, and 56 cm 8 mm is equal to 568 mm.
