Question

1. cube a has a mass of 36 grams. what is its density?

d=4.5 g/cm³ units?
cube a is made of the metal ______.

table
metal | density (g/cm³)
silver | 10.5
aluminum | 2.7
steel | 7.6
titanium | 4.5
gold | 19.3
copper | 9

Explanation:

Step1: Find the volume of Cube A

From the formula \(\frac{3V}{8}\) (assuming there was a typo and it's related to the volume, maybe the side length calculation? Wait, maybe the volume of Cube A is calculated as follows. Wait, maybe the cube has a volume related to the formula. Wait, maybe the cube's volume is \(8\) \(cm^3\)? Wait, maybe the mass is \(36\) grams, and we need to find density. Wait, density \(D=\frac{mass}{volume}\). Wait, maybe the volume of Cube A is \(8\) \(cm^3\)? Wait, let's check the density formula. Density \(D = \frac{m}{V}\), where \(m\) is mass and \(V\) is volume.

Wait, maybe the cube's volume is calculated from the formula \(\frac{3V}{8}\)? Wait, maybe the side length of the cube is \(2\) cm, so volume \(V = 2^3=8\) \(cm^3\). Then mass is \(36\) grams. Wait, no, \(36\) divided by \(8\) is \(4.5\) \(g/cm^3\). Ah, so volume \(V = 8\) \(cm^3\), mass \(m = 36\) grams. Then density \(D=\frac{36}{8}=4.5\) \(g/cm^3\).

Step2: Identify the metal from the density table

Looking at the density table: Titanium has a density of \(4.5\) \(g/cm^3\). So Cube A is made of Titanium.

Answer:

The density of Cube A is \(4.5\) \(g/cm^3\), and it is made of Titanium.
