A bookshelf has 5 shelves its made from wood that is 30 mm thick and the shelves are evenly spaced
Bookshelf is 2100mm high 600mm long and
300mm wide
Mark out the sides and shelves from a piece of wood 2400mm long and 1200mm wide a saw cut is approximately 3 mm thick
To mark out the sides and shelves of the bookshelf, we'll need to calculate the lengths of each piece and consider the saw cut thickness.
1. Calculate the length of each side:
- Since the bookshelf is 2100mm high and the wood is 30mm thick, each side piece needs to be 2100mm + 30mm + 30mm = 2160mm long.
2. Calculate the length of each shelf:
- Since the bookshelf is 600mm long and the wood is 30mm thick, each shelf piece needs to be 600mm + 30mm + 30mm = 660mm long.
3. Take into account the saw cut thickness:
- The saw cut is approximately 3mm thick. To ensure that the actual pieces will fit together correctly, we'll need to account for this additional thickness when marking out the dimensions.
4. Marking out the sides:
- Using the 2400mm length of the wood, mark two pieces that are 2160mm long each while considering the saw cut thickness. Start by subtracting the saw cut thickness (3mm) from the total length (2400mm) and mark the first piece at 2160mm. Then mark the second piece at 2160mm from the first marking.
5. Marking out the shelves:
- Using the 1200mm width of the wood, mark out each shelf that is 660mm long while considering the saw cut thickness. Start by subtracting the saw cut thickness (3mm) from the total width (1200mm) and mark the first shelf at 660mm. Then mark the second shelf at 660mm from the first marking, and continue until you have marked out all five shelves.
After marking out the sides and shelves, you can then cut along the marked lines using a saw to obtain the required pieces for the bookshelf.
