Myra draws and cuts out 8 planets for a class project she pastes each planet on a separate sheet of paper how many sheets of paper did Myra use?
From the data given in the question the only certainty is that
at least 8 sheets of paper have been used - the 8 sheets onto which
the cut-outs have been pasted.
There is no statement in the question as to on what the planets
were drawn before they were cut out.
For example the planets could have all been drawn on a single
piece of cardboard before being cut out and then pasted to a sheet
of paper: each planet having a separate sheet of paper so that they
could be attached to the wall in order from their sun with
information regarding distance from their sun, the length of their
day (in earth hours), the length of their year (in earth
days/years), etc.
Or perhaps they were drawn on a single sheet of paper, making
the total 9 sheets;
Or perhaps they were drawn on more sheets of paper - two or
three smaller planets on a single sheet - adding two or more sheets
of paper;
Or perhaps a single sheet of paper is used per planet for the
drawing, adding an extra 8 sheets.
Therefore Myra used between 8 and 16 inclusive sheers of
paper.
