How many six-inch by six-inch square tiles are needed to cover a three-foot by two-foot rectangular section of floor?
I need to convert the units of the floor dimensions from feet to inches, so I can compare them to the tile size. One foot is equal to 12 inches, so a three-foot by two-foot rectangle is equivalent to a 36-inch by 24-inch rectangle. I can use division to find how many tiles fit along each dimension of the rectangle. 36 divided by 6 is 6, so I can fit 6 tiles along the longer dimension. 24 divided by 6 is 4, so I can fit 4 tiles along the shorter dimension. To find the total number of tiles, I can multiply the number of tiles along each dimension: 6 times 4 is 24. Therefore, I need 24 tiles to cover the rectangular section of floor.
