<h3>Answer:  1350 square cm</h3>

===============================================

Explanation:

Each face of the cube is a square with side length 15. The area of the square is s^2 = 15^2 = 225. There are 6 faces, so 6*225 = 1350

------

In terms of a formula, the surface area of a cube is

SA = 6s^2

plugging in s = 15 gives

SA = 6*15^2

SA = 6*225

SA = 1350

Basically it's the same sort of steps as before.

Which angles are vertical to DEA? Question is located in the attached file (image)​
ValentinkaMS [17]

Answer:

∠CEB

Step-by-step explanation:

The vertical angle is one that is directly <em>opposite</em> to the original angle. In this image of two intersecting lines, it looks like the angle ∠CEB is directly across from our angle ∠DEA. So, the angle ∠CEB is <em>vertical to</em> ∠DEA.

Hopefully that was helpful! :)

8.3 x 10 to the 3rd power
masha68 [24]


If your looking at a number to a power (in this case, 3 [cubed]), you multiply the base by the exponent. I would start with the 10 - 10x10x10 = 1,000


Next, multiply your answer by 8.3. You now have 8,300 :)

I don’t know how to solve this problem
miss Akunina [59]

The draws are independent, so

P(\text{red then blue})=P(\text{red})\cdot P(\text{blue})

There is a total of 11 marbles in the bag, so

P(\text{red})=\dfrac3{11}

and

P(\text{blue})=\dfrac5{11}

So

P(\text{red then blue})=\dfrac{15}{121}
