23 child with dimensions of 1‘ x 1‘ she wants a towel hallway that is 8 feet long and 3 feet wide. Does she have enough towels? If not how many more does she need?
The area of the hallway is 8 feet x 3 feet = 24 square feet.
Each towel has an area of 1 foot x 1 foot = 1 square foot.
She needs 24 towels to cover the entire hallway.
Therefore, the child does not have enough towels and she needs 24 - 23 = 1 more towel.
