Question

A sugar cube has a mass of 11.2 g. Each side is 2 cm long. What is the density of the sugar cube? Hint find the volume of the cube first.

A. 1. 4g/cm^3
B. 5. 6g/cm^3
C. 8 cm
D. 4g/cm^3

Answer 1

The answer is b 5.6g/cm^3

Answer 2

Answer: A.
`1.4\ g/cm^3`

Explanation:

Given : A sugar cube has a mass of 11.2 g.

Each side is 2 cm long.

We know that the volume of the cube is given by :-

`V=\text{Side}^3`

Then, the volume of sugar cube =
`2^3=8\ cm^3`

Using formula:

`\text{Density}=\frac{\text{Mass}}{\text{Volume}}`

We have

`\text{Density}=(11.2)/(8)=1.4\ g/cm^3`

Hence, the density of the sugar cube =
`1.4\ g/cm^3`
