a)
}}}
Since the measurements were given as just 5.5 feet, 6.5 feet and 6 inches,
they do not seem to be very precise, so a scientist would say that the volume is about 18 cubic feet.
b)
A scientist would say the weight of the waterbed is about 1100 pounds.
If this was a problem in a science class, the scientist answers would be considered correct.
Your teacher may want the answers with many decimal places, even if they do not make scientific sense.
