Question

Haley wants to determine the density of an irregular block of wood. She puts the block of wood on a digital scale and finds the mass to be 36.5 grams.

Next, Haley places the block into a graduated cylinder that contains 10 mL of water. The water level rises to 34.7 mL after the block is placed in the cylinder, and Haley reports the volume of the block to be 24.7 mL.

In order to find the density of the block of wood, Haley does the following calculation:

36.5 g X 24.7 mL = 901.6 g*mL
Haley reports the density of the block of wood to be 901.6 g*mL, but her teacher tells her that the actual density of the block of wood is 1.5 g/mL. What was the source of Haley's calculation error?

Haley used the wrong technique to measure the volume of the block.

Haley reported the the mass of the block in the wrong units.

Haley used the wrong equation to calculate the density of the block.

Haley used the wrong instrument to measure the mass of the block.
