A cube has volume 15 625 cm3. what is the surface area of the cube?
bulgar [2K]
<span>SA=3750c<span>m<span>2
</span></span></span>

The volume of a cube is determined by the formula
<span>V=<span>s3</span></span> where s is the measurement of each edge.

Since cube has six square faces, each of the faces will have the area of a square which we know to be <span>A=<span>s2</span></span>. Therefore the total surface area of a cube will be the area of a square multiplied by six (faces).

<span>SA=6<span>s2</span></span>

Solving for the length of edge (side):

<span>V=<span>s3</span></span>

<span>s=<span>3<span>√V</span></span>=<span>3<span>√<span>15625c<span>m3</span></span></span></span></span>

<span>s=25cm</span>

Solving for the surface area:

<span>SA=6<span>s2</span>=6<span><span>(25cm)</span>2</span></span>

<span>SA=3750c<span>m<span>2</span></span></span>

Doe anyone know this? At least someone have to
Paul [167]

Answer:

While I will not give you an answer, I will tell you how to find it. Don't get scared! I promise it's not complicated. You basically only need to do subtraction.

Concept Explanation:

Okay, so let's start off by defining "complement" and "supplement":

"Complement" - <em><u>complementary angles</u></em>: two angles whose sum equals 90°

"Supplement" - <u><em>supplementary angles</em></u>: two angles whose sum equals 180°

So, this question is asking you what the <u>other angle</u> is. Based on whether they ask you for the <em>complement</em> or <em>supplement</em>, you only need to subtract the first angle they give you from 90° (if it's asking for the complement) or 180° (if it's asking you for the supplement).

Here are some examples if you're still confused!

--------------------------------------------------------------------------------------------------------------

- What is the complement of a 32° angle?

↓

Since they're asking for the <u>complement</u>, we will subtract 32° (the angle they give us) from 90° (because it's a <u>complement</u>)

↓

90 - 32 = 58

↓

So our answer is: <u>58°</u>

--------------------------------------------------------------------------------------------------------------

Now let's do a supplement one.

--------------------------------------------------------------------------------------------------------------

- What is the supplement of an 84° angle?

↓

Because they're asking for the <u>supplement</u>, we will subtract 84° (the angle they give us) from 180° (because it's a <u>supplement</u>)

↓

180 - 84 = 96

↓

Then our answer will be: <u>96°</u>

--------------------------------------------------------------------------------------------------------------

That's all! It's just some subtraction once you know what the vocabulary means. Please comment if you have any other questions.

If you want me to check your answers once you try your problem, I can do that as well!

FInd the slope of the line passing through the points (0,4) and (-8,-1)
Yuliya22 [10]

We can use the slope formula:

\frac{y.2 - y.1}{x.2 - x.1} = m

By plugging the values into this formula, we can solve for the slope.

-1 - 4 / -8 - 0

-5 / -8

Because there are two negatives, they cancel out;

The slope is 5/8
