Scarlet-Camille needs three lengths of wood to finish a project. She needs one piece measuring 148
cm, one piece measuring 38 cm, and one piece measuring 42 cm. Every time Scarlet-Camille cuts a length of
wood she loses 3 mm of wood. If Scarlet-Camille can only purchase lumber in full feet, how much wood does
she need to buy for the project?
I don't understand the losing 3 mm thing please help!
3 mm = 0.3 cm
Add 0.3 cm to each piece.
148.3 + 38.3 + 42.3 = 228.9 cm

I'd be happy to help explain the losing 3 mm concept.
When Scarlet-Camille cuts a length of wood, she loses 3 mm (millimeters) of wood each time. This means that the actual length of the wood she gets is slightly shorter than the original length.
In the given problem, Scarlet-Camille needs three lengths of wood measuring 148 cm, 38 cm, and 42 cm. However, every time she cuts a piece, she loses 3 mm of wood.
To calculate the actual length of wood Scarlet-Camille needs to buy, we need to account for the loss of 3 mm each time she cuts. Let's calculate the total loss due to cutting for each piece of wood:
For the piece measuring 148 cm, the loss would be 3 mm.
For the piece measuring 38 cm, the loss would also be 3 mm.
For the piece measuring 42 cm, the loss would be another 3 mm.
To calculate the total loss, we add up these three sets of 3 mm:
3 mm + 3 mm + 3 mm = 9 mm.
Now that we know Scarlet-Camille will lose a total of 9 mm throughout all of her cuts, we can subtract this from the total length of wood she needs to purchase.
Let's calculate the total length of wood she needs to purchase by adding up the original lengths of the three pieces:
148 cm + 38 cm + 42 cm = 228 cm.
However, since the problem states that we can only purchase lumber in full feet, we need to convert the length from centimeters to feet.
1 cm is equal to 0.0328084 feet (approximately).
So, the total length in feet would be:
228 cm * 0.0328084 = 7.48031472 feet.
Since we can only purchase full feet, Scarlet-Camille needs to purchase 8 feet of wood for the project.
Therefore, the answer to the question "how much wood does she need to buy for the project?" is 8 feet.
