Answer:
8.1 x 10^7 would be you answer.
Each strip is 29 cm
------------------------------------------------------
Change the m to cm
------------------------------------------------------
6 m = 600 cm
------------------------------------------------------
Find the number of strips for 1 6m-board
------------------------------------------------------
Find the number of strips that can be cut from the 6m board.
600 ÷ 29 = 20 pieces remainder 20cm
So we can only cut 20 pieces of 29 strips from one 6m board.
------------------------------------------------------
Find number of boards needed
------------------------------------------------------
70 ÷ 20 = 3.5
We need 3.5 of the 6m boards.
Since she can't have half a board, she has to buy 4 pieces of the board.
------------------------------------------------------
Answer: 4 pieces of the 6m board.
