Answer:
The mass of the second cube is about 1085.07 grams.
Step-by-step explanation:
I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.
First, find the density of this cube:

where d is density, m is mass, and v is volume.
We have one of those, but we also need volume. The volume of a cube is just:

where a is the length of a side.

The volume of this cube is 1.728cm³. Now, you can find the density;

The density of this material is about 8.68 grams per cubic centimeter.
Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:

The volume is 125cm³. Given the density and the volume, you can calculate the mass:

The mass of the second cube is about 1085.07 grams.
Answer:
The height of the cone is 
Step-by-step explanation:
we know that
The volume of the cone is equal to

where
B is the area of the circular base of the cone
h is the height of the cone
In this problem we have


<em>Find the area of the base B</em>

substitute the value of r

<em>Find the height of the cone</em>


assume 

<span>3n-8+2(5n+3)=8n+5+4n first I will do the multiplication
3n-8+10n+6=8n+5+4n Now I will simplify
13n -2 = 12n +5 Now I will add 2 to both sides
13n = 12n + 7 then I subtract 12n from both sides
n = 7</span>
(x,y) order. Point A is facing 5 where y is so it would 5 because Point A is across the y -axis.
Answer:
1.33
Step-by-step explanation:
62 can only be subtracted from 82 once. So 82.46-62 would be 20.46. Since you can't subtract anymore you put a decimal point. 62x3=186 and 20.46-186=1.86 and you can subtract 186-186=0.
