There are 2.54 centimeters in 1 inch. How many centimeters are there in 1 foot? In 1 yard? Explain your reasoning.
Dmitry [639]

1 inch = 2.54 centimeters

1 foot = 12 inch

1 inch = 2.54 cm

12 inch = 12times 2.54 cm = 30.48 cm

Answer 1 foot = 12 inch = 12times 2.54 = 30.48 cm

* we know 1 yard = 3 foot

1 foot = 12 inch

1 inch = 2.54 cm

Answer : so 1 yard = 3 foot = 3* 12 inch = 36 * 2.54 cm =91.44 cm
