Question

a piece of aluminum weighs 450 grams, and the density of aluminum is 2.5 g/cm³. what is the volume of the aluminum? use the keypad to enter your answer in the box. the piece of aluminum has a volume of cubic centimeters.

Explanation:

Step1: Recall the density formula

Density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume. We need to solve for $V$, so $V = \frac{m}{
ho}$.

Step2: Substitute the given values

Given $m = 450$ grams and $
ho=2.5$ g/cm³. Then $V=\frac{450}{2.5}$.

Step3: Calculate the value

$450\div2.5=\frac{450\times2}{2.5\times2}=\frac{900}{5} = 180$.

Answer:

180
