The grass in the outfield of a professional baseball stadium is trimmed to a height of 5.08 x 10^-5 miles.

Which unit of measurement is most appropriate to measure this height?

A. feet

B. kilometers

C. meters

D. inches

Option D is the correct answer.

Explanation:

Height of grass = 5.08 x 10⁻⁵miles

Feet

1 mile = 5280 feet

Height of grass = 5.08 x 10⁻⁵x 5280 = 0.268 ft

Kilometers:

1 mile = 1.6 km

Height of grass = 5.08 x 10⁻⁵x 1.6 = 8.128 x 10⁻⁵ km

Meters:

1 mile = 1600 m

Height of grass = 5.08 x 10⁻⁵x 1600 = 0.0812 m

Inches:

1 mile = 63360 inches

Height of grass = 5.08 x 10⁻⁵x 63360 = 3.22 inches

From seeing the result it can be understood that inch is the best unit to measure the height of grass.

Option D is the correct answer.
