please help me.dont spam. explain clearly​

Answer 1

Answer:

$980g$

Step-by-step explanation:

The formula here is

$density = \frac{mass}{volume}$

Here the density and volume is given. So,

$19.6 = \frac{mass}{50}$

Therefore,

$mass = 19.6 \times 50 = 980$

Since the units are in g/cm³ and cm³ the mass of gold is 980g or 0.98 kg

Sides of the Cube

Since all sides of a cube are equal, the volume of a cube is

s

, where

s

is one side. If you have the volume of the cube, you can take the cube root of the volume to find the value of each side of the cube.
