Question

What is the density of a cube that has a mass of 25 grams and a volume of 125 cm3​

Answer 1

Question:- What is the density of a cube

Given:-

1. Mass = 25 grams
2. Volume = 125 cm³

Answer:-

Formula :-

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

`Density = (25)/(125) \frac{grams}{cm {}^(3) } \\ Density = \frac { \cancel{25} {}^( \: \: 1) }{ \cancel{125} ^( \: \: \: 5) } = 0.2 \: g \: cm^( - 3)`

To convert it in Kg/m³ divide by 1000 and multiple with 10⁶

`Density = 0.2 \: * \frac {{10}^(6) }{10 {}^(3) } = 0.2 * {10}^(3) \\ Density = 200 \: kg \: m {}^( - 3)`
