1.69 The “Western Stone” in Jerusalem is one of the largest stone building blocks ever to have been used. It has a mass of 517 metric tons and measures 13.6 m long, 3.00 m high and 3.30 m wide. What is the density of this rock in g/cm3? (1 metric ton 1000 kg)

Interpretation Introduction

To determine:

The density of the block.

Explanation of Solution

Step 1:

The volume of the block.

The volume can be found by using the next equation:volume = lenght x width x thickness

To change from meters to centimeters use the proper conversion factor:1 meter = 100 centimeters

The length of the block is 13.6 meters.13.6 m x 100 cm1 meter= 1360 cm

The width of the block is 3.3 meters.3.3 m x 100 cm1 meter= 330 cm

The thickness of the block is 3.0 meters3.0 m x 100 cm1 meter= 300 cm

volume = 1360 cm x 300 cm x 330 cm = 134640000 cm3

Step 2:

The density of the block.

Density is the ratio of the mass to the volume of a substance
