How do you find a side length of a cube with the surface area of one face (64cm)

1 answer:

7 0

Fact #1:
A cube has six faces.

Fact #2:
Every one of them has the same area.

Fact #3:
The surface area of each face is (the length of the cube's side)²

Now that I look at this one more carefully, the only thing you need to know
to solve it is Fact #3. (But you can keep the others and save them for later.)

The surface area of each face is (the length of the cube's side)²

64 is the (length of the cube's side)²

Can you find a number that gives you 64 when you multiply it by itself ?
That's the length of the cube's side.

Hint: If you don't get ' 8 ', work on it a little more.

A company sells cookies in 250-gram packs. When a particular batch of 1,000 packs was weighed, the mean weight per pack was 255

AURORKA [14]

Let X be a random variable representing the weight of a pack of cookies.
P(X < 250) = P(z < (250 - 255)/2.5) = P(z < -5/2.5) = P(z < -2) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275 = 2.3%

Therefore, we conclude that about 2.3% of the packs weighed less than 250 grams.

What is the measure of ∠x?

Archy [21]

Answer:

114 degrees

Step-by-step explanation:

Hi there.

Line segment LN is a straight line, meaning that it contains a straight angle (an angle measuring 180 degrees).

We know that if this is a straight angle, that $x+66=180$ .

Therefore, m∠x = 114 degrees.

Hope this helps! :^)

You live on a triangular piece of land with a base of 121 yards and

morpeh [17]

The area of triangular piece of land in acres is 1 acre.

Further Explanation:

In order to find the area of the triangular piece of land in acres we have to find the area in yards

<u>Given:</u>

Base = 121 yards

Height = 80 yards

$Area = \frac{1}{2} * base * height\\ = 0.5 * 121 *80\\=4840\ square\ yards\\Square\ Yards\ in\ one\ acre=4840\ square\ yards\\So,\\Area\ in\ acres = \frac{4840}{4840} \\= 1\ acre$

So, the area of triangular piece of land in acres is 1 acre.

Keywords: Area of triangle, conversion from yards to acre
