Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.
