Final answer:
To find the length of each piece, divide the total length of the plank by the number of pieces. In this case, each piece would be 0.4 meters long.
Step-by-step explanation:
To find the length of each piece that a 2.8m long plank of wood is cut into when divided into 7 equal pieces, you would divide the total length of the plank by the number of pieces. Here's the calculation step-by-step:
- Determine the total length of the plank: 2.8 meters.
- Determine the number of pieces: 7 pieces.
- Divide the total length by the number of pieces: 2.8m / 7.
- Complete the division to find the length of each piece.
So, 2.8m divided by 7 equals 0.4m. Therefore, each piece of wood will be 0.4 meters long when the plank is cut into 7 equal pieces.
