Question

franz needs to measure the mass of an iron cube about the size of a table tennis ball. which units are most appropriate for him to use? nanograms grams kilograms

Explanation:

A table - tennis - ball - sized iron cube is a relatively small object. Nanograms are extremely small units (1 nanogram = \(1\times10^{-9}\) grams) and are not practical for measuring such an object. Kilograms are too large for a small iron cube (1 kilogram = 1000 grams). Grams are a commonly used unit for measuring the mass of small objects.

Answer:

grams
