• Do you think that the estimation will be an over- or under-estimate, or will it be exactly correct? Or will it be impossible to say without more information? Be as clear as you can with your reasoning.
• Why do you think that the solver made the estimate in this way? What assumptions were made?
• How close do you think that the estimations would be to the real values?

1. I wish to estimate the volume of an apple. It weighs 76.2kg. I therefore estimate its volume to be 76.2cm$^3$.
2. I have a set of ball bearings of volume 1cm$^3$. A large crate is filled to the brim with ball bearings and closed with a lid. The box contains 850 ball bearings, so I estimate that the box has a volume of 850cm$^3$.
3. An oak tree measures 106cm around the base, corresponding to a cross section of 0.0894m$^3$. I have measured the height to be 7.3m. I estimate the volume to be 0.65m$^3$. How would your answer differ if the question related to a fir tree (with the same numbers)
4. In a wood of area 27000m$^2$ I find 34 earthworms in a volume of soil of 1m$^2$ in area and 20 cm deep. I therefore estimate that there are 918000 earthworms in the wood.

1. I wish to estimate the volume of an apple. I weight it and measure 76.2g. I therefore estimate that its volume is 76.2 cm³.
2. I have a set of ball bearings of volume 1cm³. A large box is filled to the brim with ball bearings and closed with a lid. The box contains 850 ballbearings, so I estimate that the box has a volume of 850 cm³.
3. An oak tree measures 106 cm around the base, corresponding to a cross section of 0.0894 m². I have measured the height to be 7.3m. I estimate its volume to be 0.65m³. How would the results differ if a fir tree exhibited the same dimensions?
4. In a wood of area 27000m² I find 62 woodlice in an area of 1m². T
