Question

1. the empire state building in new york city was for many years the tallest building in the world. its height, including a television mast added in 1951, is 490.7 yards. convert this measurement to cm. (1.000 m = 39.37 inches)

Explanation:

Step1: Convert yards to inches

We know that 1 yard = 36 inches. So for 490.7 yards, the number of inches is $490.7\times36$ inches.
$490.7\times36 = 17665.2$ inches

Step2: Convert inches to cm

Given that 1.000 m = 39.37 inches, and 1 m = 100 cm. So 1 inch=$\frac{100}{39.37}$ cm.
The height in cm is $17665.2\times\frac{100}{39.37}$ cm.
$17665.2\times\frac{100}{39.37}=\frac{1766520}{39.37}\approx44869.7$ cm

Answer:

44869.7 cm
