Question

4 fill in the blanks. 1 foot is exactly ____ inches 1 yard is exactly ____ feet 6 circle the traditional unit that would be the best choice for measuring the length of a skateboard? feet inches miles yards 8 circle the traditional unit that would be the best choice for measuring the length of the california coastline? feet inches miles yards 10 if your cat is 1.5 feet long from head to tail, estimate how many centimeters long he is.

Explanation:

Step1: Convert feet to inches

Since 1 foot = 12 inches, so 1 foot is exactly 12 inches.

Step2: Convert yard to feet

Since 1 yard = 3 feet, so 1 yard is exactly 3 feet.

Step3: Choose unit for skateboard length

A skateboard is about 3 feet long. Inches would make the number too large (36 inches), miles and yards are too large for this small - scale measurement. So the best unit is feet.

Step4: Choose unit for California coastline length

The California coastline is very long. Feet, inches and yards are too small for measuring such a long distance. Miles are a more appropriate unit for large - scale length measurements.

Step5: Convert feet to centimeters

We know that 1 foot ≈ 30.48 centimeters. For a cat that is 1.5 feet long, we use the formula \(L = 1.5\times30.48\). \(1.5\times30.48=(1 + 0.5)\times30.48=30.48+15.24 = 45.72\) centimeters.

Answer:

1 foot is exactly 12 inches.
1 yard is exactly 3 feet.
For the skateboard, circle feet.
For the California coastline, circle miles.
The cat is approximately 45.72 centimeters long.
