1gcm-³ = 1000kgm-³
so 2.7gcm-³ = 2700kgm-³ (density)
volume = 1×0.6×0.3m³ = 0.18m³

mass = density ×volume = 2700×0.18 Kg = 486Kg

What is 3x^2-2n-5=0<br> please help me!!!
expeople1 [14]
The answer to your question is: 
It is a quadratic equation in 'x', with 'n' mistakenly typed in the second term..

Although you didn't ask for the solutions to the equation, I'm already here
so I might as well go through it and find them:

<span><u>3x² - 2x - 5 = 0</u></span>

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

<u>x = -1</u>
and
<u>x = ⁵/₃</u>
