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...

The dimensions of the room are given in feet. The dimensions of the block are in centimeters. A conversion factor between feet and centimeters is required. The table inside the back cover of the textbook gives this number: 2.54cm = 1 in.

Since the conversion factor is between inches and centimeters and the data is in feet we must also use an additional conversion factor: 12 inches = 1 foot.
