Answer 1

To calculate the height in centimeters for a height of 3 feet and 4 inches, convert each measurement to centimeters and add them together. The total height is 102 cm when rounded to 0 decimal places.

Step-by-step explanation:

To calculate the height in centimeters of someone who is 3 feet and 4 inches tall, we need to convert feet and inches to centimeters using the given conversion factors: 30.5 cm for 1 foot and 2.5 cm for 1 inch.

First, we convert the feet to centimeters:

• 3 feet x 30.5 cm/foot = 91.5 cm

Then, we convert the inches to centimeters:

• 4 inches x 2.5 cm/inch = 10 cm

Finally, we add the two results together to get the total height in centimeters:

• 91.5 cm + 10 cm = 101.5 cm

Rounding off to 0 decimal places, the total height is 102 cm.
