<h3>The volume of cube is 729 cubic centimeter</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>

Where, "a" is the length of side of cube
Given that, surface area = 486 square centimeter

<u><em>Find the volume of cube:</em></u>

Thus volume of cube is 729 cubic centimeter
Sally = 1/3
Jerry = 5/6
David = 1/2
Mona = 1 - 7/8 = 1/8
So, the biggest fraction among them is 5/6.
Jerry has completed the most work time.
Answer:
6
Step-by-step explanation:
1. get rid of parentheses: 12x -6 = 10x +6
2. group like terns together: 12x-10x = 6+6
3. simplify: 2x = 12
4. divide both sides by 2: x=6
You find a parallelogram area by this formula:

Where
b is its base and
h, its height.
You get
b's value applying distance between two points formula.
If A and B points form the base:

And
h is the perpendicular distance between both bases.
