Real-Life Math -- Solution

First, figure out the needs for the 19th floor. Start by converting yards to inches.

1,200 yards x 3 feet per yard = 3,600 feet
3,600 feet x 12 inches per foot = 43,200 inches

Now, how many bolts will that take?

43,200 / 5 = 8,640 bolts

Now the top floor. First, the conversion.

800 yards x 3 feet per yard = 2,400 feet
2,400 feet x 12 inches per foot = 28,800 inches
28,800 / 4 = 7,200

Now, the total.

8,640 + 7,200 = 15,840

You'll need 15,840 bolts in all.
