Question

Tim wants to boil rice on the stove. He needs to use exactly $3$ gallons of water in a pot to boil the rice. Which method should Tim use to most accurately measure the water?

• A. Tim should use a $100$ gallon barrel to fill water into the pot.
• B. Tim should use a $1$ gallon jug to fill water into the pot.
• C. Tim should use a teaspoon to fill water into the pot.
• D. Tim should fill water in his palm and pour it into the pot.

Answer 1

The correct option is B

Tim should use a $1$ gallon jug to fill water into the pot.

Explanation of correct option:

Option B:

Tim should use a jug which can exactly measure $3$-gallon water into the pot.

So, he should use a jug with a capacity less than $3$-gallons, but not too less

So from the given options, $1$-gallon jug is perfect.

Option B is correct.

Explanation of in-correct option:

Option A:

Tim cannot use a $100$-gallon barrel because it is too large and it is not possible to measure exact $3$-gallons of water into the pot.

Option A is incorrect.

Option C:

Tim cannot use a teaspoon because it is too small and it is very difficult to measure exact $3$-gallons of water into the pot using it.

Option C is incorrect.

Option D:

Tim cannot use his palm because it is not an accurate measuring instrument and he cannot measure exact $3$-gallons of water into the pot using it.

Option D is incorrect.

Hence, option B is correct.
