Question

An inground swimming pool contains 2.3 times 10 Superscript 4 units of water. Which unit of measure was used?

Answer 1

Answer:

  a) gallons

  b) gallons

Step-by-step explanation:

a)

1 fluid ounce is about 6 teaspoons or 30 cubic centimeters or 1.8 cubic inches. 2.3×10^4 fluid ounces is less than 1 cubic yard. We suspect the pool is much larger than that, so its volume is probably measured in gallons.

b)

Of the units listed, only teaspoons and gallons are units of volume. As we saw in the previous problem, a teaspoon is a pretty small volume in relation to the size of most fish tanks. The appropriate unit of measure would be gallons.
