Question
1 A rectangular block of steel measures 4 cm x 2 cm x 1.5 cm. Its trass is 93.6g.
Calculate the density of steel.
b Steel is made almost entirely of iron atoms, but it is denser than iron.
Suggest a reason for this.

Answer 1

Answer:

$d=7.8\ g/cm^3$

Step-by-step explanation:

Given that,

The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm

Mass, m = 93.6 g

We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,

$d=\dfrac{m}{V}\\\\d=\dfrac{93.6}{4\times 2\times 1.5}\\\\d=7.8\ g/cm^3$

So, the density of the steel is $7.8\ g/cm^3$.
