Answer:

The probability is 25%

Step-by-step explanation:

If you need an even number on your first roll, theres 3 numbers you can get(2, 4 ,6) . So the probability is 3 out of 6(50%).

If you need an odd number on your second roll, there's also 3 numbers you can get(1, 3, 5). So the probability is 3 out of 6(50%).

0.50 times 0.50 = 0.25

So your answer is 25%

First you need common denominator
x/2 - 6/2 = 34/2

Question 1: find the volume of a cube whose total surface area is 486cm^2
lapo4ka [179]
<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>

Surface\ area = 6a^2

Where, "a" is the length of side of cube

Given that, surface area = 486 square centimeter

486 = 6a^2\\\\a^2 = \frac{486}{6}\\\\a^2 = 81\\\\a = 9

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

volume\ of\ cube = a^3\\\\volume\ of\ cube = 9^3\\\\volume\ of\ cube = 9 \times 9 \times 9\\\\volume\ of\ cube = 729

Thus volume of cube is 729 cubic centimeter
