(Hint: 1 foot = 12 inches)

	Building 1	Building 2	Building 3

Amount (inches)	228	344	444

• A. Building 1
• B. Building 3
• C. None of the above
• D. Building 2

Answer 1

The correct option is D Building 2

Building 1 height = 19 feet
Building 2 height = 29 feet
Building 3 height = 37 feet

• 1 foot = 12 inches
• To get the height in inches, multiply 19 feet with 12, as 1 foot is equal to 12 inches.
• For building $1:19\times 12=228$ inches Thus, there are 228 inches in 19 feet.
• To get the height in inches, multiply 29 feet with 12, as 1 foot is equal to 12 inches.
• For building $2:29\times 12=348$ inches Thus, there are 348 inches in 29 foot.
• To get the height in inches, multiply 37 feet with 12, as 1 foot is equal to 12 inches.
• For building $3:37\times 12=444$ inches Thus, there are 444 inches in 37 foot.
• The shown height of building 2 in the table is 344 inches, which is incorrect.

Hence, the height of building 2 has an error in the conversion.
