Answer: it’s 93cm^

Step-by-step explanation:

remember that the bottom of the triangular prism/top base don’t count as surface area.

first equation for the surface of the triangular prism: 1/2ps = 1/2•12•4 = 24m

add it to the surface area of the rectangular prism: 3•3 + 5•3•4 = 69m

then simply add them

your answer is 93m^!

enjoy :))

Calculate the distance between each given pair of points. Round your answer to the nearest tenth, if necessary.
Ksju [112]
The answer is 5 

Here are the steps:

First off, we will be using the distance formula of 
d=\sqrt{(x_ {2}- x_{2}) ^{2}+( y_{2}- y_{1})^2     }

So we have the ordered pairs of (3,1) and (6,5)

Once you plug them into the formula it should look like this: 
d= \sqrt{(6-3)^2+(5-1)^2}

Now we do the math inside the parenthesis and end up with:
d=\sqrt{3^2+4^2}

Then you multiply by the power and simplify to get:
d=\sqrt{25}

And the \sqrt{25}=5

So your answer is 5
