Answer:
1 doller and 25 cents so easy
Step-by-step explanation:
<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
2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2
