Answer

Yes, 180 cm is approximately 5 feet and 11 inches

Work Step by Step

If we use the conversion rate $1\text{ft}=12\text{ in}$: $5\text{ ft } 11\text{ in}= 5\times 12 \text{ in}+11 \text{ in}=71 \text{ in}$ Now we can convert from inches to centimeters to check the equivalency, we have to consider the following conversion rate: $1\text{ in}= 2.54 \text{ cm}$ We multiply both sides by 71 in order to get the answer to the question: $71 \text{ in} =71\times 2.54 \text{ cm} = 180.34 \text{ cm}$ Yes, 180 cm is approximately 5 feet and 11 inches.
