Question

Sasha is making some shelves which are 75.5 cm long. If the wood she is using is 180 cm long, how many pieces will she need to make six shelves?

Answer 1

3

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.
