ACT-Based Science: Measuring Density and Material Identification Answer Key

Applied Science Problem:

A student measures a metal cube with a digital caliper and finds its volume to be 8 cm³. Using a digital scale, the mass is determined to be 64 grams. What is the density of the cube?

2 g/cm³

4 g/cm³

8 g/cm³

10 g/cm³

(Correct Answer: C – Density = mass/volume = 64g ÷ 8cm³ = 8 g/cm³.)
