12 pieces each 13 3/8 inches long need to be cut from a board 16 feet long. How much is left after the 12 pieces are cut? ______ inches
I got 31 and was wondering if i was right?
Well, 16 feet = 192 inches.
13_3/8 x 12 = 160_1/2 inches.
192 inches - 160_1/2 inches = 31_1/2 inches.
You can also write it as 31.5 inches.
You forgot the 1/2.
Other than that, good job!
I had that to just forgot to write down the 1/2. Thank you
To determine how much is left after cutting 12 pieces each 13 3/8 inches long from a board 16 feet long, we need to calculate the length of the 12 pieces and subtract it from the original length of the board.
First, let's convert the length of the board from feet to inches. Since there are 12 inches in 1 foot, we can multiply 16 feet by 12 to get the length in inches:
16 feet * 12 inches/foot = 192 inches
Next, let's calculate the total length of the 12 pieces. Each piece is 13 3/8 inches long, so we multiply this by 12:
(13 3/8 inches) * 12 = 160 1/8 inches
Finally, we subtract the total length of the 12 pieces from the original length of the board to find out how much is left:
192 inches - 160 1/8 inches = 31 7/8 inches
Therefore, after cutting the 12 pieces, there will be 31 7/8 inches left, not just 31 inches.
