square feet (ft') of floor space. How many square meters of area are there?
You've been asked to calculate the mass of a conical pile of sawdust measuring 10 meters high with a base
radius of 8 meters. From experimental measurements, you've been able to determine that the density of
the sawdust depends upon the depth, d, of the sawdust in meters, according to the equation
p(d) = 180 + 10d kg/m³. Find the mass of the pile.
1877.33
x kg
According to the rules on significant figures, the product of the measured quantities 99.9 m and 1.008 m should be expressed to three significant figures- 101 m2. Yet, in this case, it would be more appropriate to express the answer to four significant figures- 1.007 m2. Explain why.
