Step 1
Read the problem twice. On the first pass, note
the general concepts needed to find the answer. On the second pass
note the details.
The problem
The Berliner Lecture Room (PSB 180) at Bryn Mawr College is
approximately 42.8 feet long by 26.3 feet wide by 11.6 feet tall.
This room is filled with cubic blocks. Each block is 0.75 cm/side and
has a mass of 15 grams. The room is filled with blocks. What would
be the total mass of the blocks required to fill the room (assume
partial blocks may be obtained).
You may be thinking...
During the first reading of the problem you might notice that
a mass must be calculated. You may also notice that dimensions are
given for each block and also for the total room and that the
dimensions for each are different (feet vs centimeters).
During the second reading of the problem you might begin to
consider how you could relate the size of the room to the mass of the
blocks. You might also consider that a conversion between centimeters
and feet is likely to be necessary.
