Where it goes
The boards
Every size in millimetres. It all comes from one plank 150 wide, 15 thick and 1.8 m long.
Left end
150 × 120 × 15120 wide, 150 high, 15 thick, with a hole 20 across.
On the floor at the left end, 15 in from the front and the back. The hole is in the middle, 30 down from the top.
Right end
150 × 120 × 15The same as the left end, hole and all.
On the floor at the right end, 15 in from the front and the back.
Stuck?Show a hint
The ends stand between the front and the back, so they're 150 − 15 − 15 = 120 wide. A copy of a component is the same part again, its hole and all.
