Question 28
H

A student finds the density of a small metal cube.

The student measures one side of the cube as 1.2 cm using a ruler marked in millimetres. The student measures the mass on a balance that reads to 0.01 g.

Which change would most improve the accuracy of the density value?

[1]
A

Measure the side with a micrometer instead of the ruler

B

Find the volume by displacement in a 100 cm3100\ \text{cm}^3100 cm3 cylinder

C

Use a balance that reads to the nearest 1 g1\ \text{g}1 g instead

D

Use a balance with a larger maximum mass than the current one
