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

I was thinking No because 1 foot= 12 inches and so 12 x 8=96 so she didn't buy enough lumber?
(Please correct me if I'm wrong. )



Answer :

1 foot= 12 inches
12*8= 96 inches.
Christy didn't buy enough lumber because 8 foot is less than 100 inches. * foot equals 96 inches and it is less than 100 inches.
