The dimensions of a square prism are 2 centimeters by 2 centimeters by 12 centimeters. What is its surface area?

Pani-rosa [81]

Answer:

The surface area of the square prism is $104\ cm^{2}$

Step-by-step explanation:

we know that

The surface area of the square prism is equal to

$SA=2b^{2} +4bh$

where

b is the length side of the square base

h is the height of the prism

In this problem we have

$b=2\ cm$

$h=12\ cm$

substitute

$SA=2(2)^{2} +4(2)(12)=104\ cm^{2}$

Aidan writes numbers on his ten fingers as 5, 7, 9, 11, 13, 15, 16, 19, 22, 23. What is the probability of picking an even numbe

faltersainse [42]

It would be 2/10, or 1/5, since two out of the 10 numbers are even. 2/10 simplifies to 1/5, since there is 1 for every 5 numbers.

We could turn this into a percentage by dividing 1 by 5, which gives us 0.2. Then we can multiply by 100 to get 20.

So, our probability of choosing an even number is:
2/10
OR
1/5
OR
20%

Hope I could help!
