Todd has a board that is 6 ft. 3in. He needs to cut it to 4 ft. 9 in. How much should he cut off?
6 ft., 3 in = 5 ft, 15 in
(5 ft, 15 in) - (4 ft, 9 in) = ?
4ft
To determine how much Todd should cut off, we need to find the difference between the initial length of the board and the desired length.
First, let's convert 6 ft. 3 in. into inches. Since there are 12 inches in a foot, we can multiply 6 by 12 and then add 3 to get the total inches.
6 ft. = 6 * 12 = 72 inches
6 ft. 3 in. = 72 inches + 3 inches = 75 inches
Similarly, let's convert 4 ft. 9 in. into inches.
4 ft. = 4 * 12 = 48 inches
4 ft. 9 in. = 48 inches + 9 inches = 57 inches
Now, to find how much Todd should cut off, we subtract the desired length from the initial length:
75 inches - 57 inches = 18 inches
Hence, Todd should cut off 18 inches from the board to make it 4 ft. 9 in.
