Question

A block has dimensions 1.0 dm, 4.2 cm, and 25 mm, with a mass of 5.326 kg. Calculate the density of this block in g/cm 3 .

Answer 1

1 dm equals about 10 cm

25 mm equals 2.5 cm

and then we have 4.2 cm, including a mass of 5.326 kg

How do we find the density of the block?

First, lets rewrite our formula.

d = mass divided by volume.

lets multiply 10 cm x 2.5 cm x 4.2 cm

this equals 105.

Now, lets turn 5.326 kg into what we need to divide.

1000 cm x 5.326 kg is 5326 cm

now lets do 5326 into 105

thats 50.

Step-by-step explanation:

50 is the answer.
