Christy bought an 8 foot piece of lumber to trim a bookshelf  . Altogether, she needs 100 inches of lumber for the trim .Did Christy buy enough lumber? Explain

Sagot :

The answer is No. Christy needs 100 inches of lumber. She bought an 8 ft piece of lumber. Let's convert 8 ft to inches. 1 ft = 12 in. 8 ft = 8 * 12 in = 96 in. So, Christy has 96 inches of lumber, but she needs 100 inches of lumber. This means that she needs 4 inches more than she has (100 in - 96 in = 4 in).
