Question 1041469: A king-size waterbed mattress measures 5.5 feet by 6.5 feet by 6 inches deep. To the nearest pound, how much does the water in this waterbed weigh? (Water weighs about 63 pounds per cubic foot.)
a) Volume of the waterbed
b) Weight of the waterbed

You can put this solution on YOUR website!
a) 6in%2A%281ft%2F%2212+in%22%29=0.5ft
Volume=%285.5ft%29%2A%286.5ft%29%2A%280.5ft%29=17.875cubicfeet=17.875ft%5E3}}}
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) %2817.875ft%5E3%29%2A%2863lb%2Fft%5E3%29=1126.125lb
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.
