Hello!

To find surface area, all you need to do is add up the areas of all the faces of the prism. Let’s start by remembering some basic area formulas:

Area of a triangle= 1/2*base*height
Area of a rectangle= length*width

First, find the area of each of the little triangles on the sides of the net. The base is 3 ft, and the height is 4 ft. So:

1/2*3*4= 6 ft

There are two triangles of the same size, so multiply that number by 2.

6*2=12

Now, find the area of the top rectangle:

3*8= 24

And the area of the bottom rectangle:

5*8= 40

Finally, add all of those numbers together:

12+24+40= 76 ft^2

That should be your answer!

If it is assumed that the heights of men are normally distributed with a standard deviation of 2.5 inches, how large a sample sh
Volgvan

Answer:

30 men

Step-by-step explanation:

In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:

0.90 < Z\frac{s}{\sqrt{n}}

Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:

0.90 > 1.960\frac{2.5}{\sqrt{n}}\\n >(\frac{1.960*2.5}{0.9})^2\\n>29.64

Rounding up to the nearest whole number, the sample size should be at least 30 men.
