A mete stick is shorter than the student. So by using it, she will be force to take the measurements twice then add then together to get her height. This increases the chances of making errors. To improve the accuracy she should change the measuring instrument and use a tape measure. This will allow her to make only one measurement.
Question 3
Volume = length × width × height
= 105 × 75 × 80.5
= 633,937.5 cm³
In scientific notation;
633,937.5 cm³ = 6.339375 × 10⁵ cm³
