Question

which is a better estimate for the volume of a bottle of hair spray? 48 cups 48 teaspoons

Explanation:

First, convert units for comparison: 1 cup = 48 teaspoons, so 48 cups = 48×48 = 2304 teaspoons. A typical hair spray bottle holds around 100-300 mL; 1 teaspoon ≈ 5 mL, so 48 teaspoons ≈ 240 mL, which matches typical hair spray volume. 48 cups is far too large (≈11.36 L).

Answer:

48 teaspoons
