Answer: 303.2
Step by step
1) use L•W•H to find the first half of the prism
2) 20.6 • 3.8 • 2.9 = 227.012
3) 7.1 • 3.7 • 2.9 = 76.183
4) 227.012 + 76.183 = 303.19500

I'm offering 10 points, only answer if you're smart
Vera_Pavlovna [14]
Challenge accepted!!
This is more simple than you think, it's actually quite similar to that of diameter and radius, except this is triangles instead of circles. 

The "centroid" of a triangle is known as the center of mass, everything around it is perfectly evenly balanced from that point, and for triangles, it's the point of intersection for all medians. Now, when dealing with the centroid of triangles, there is a rule that always applies to every median: the distance from a vertex of the triangle to the centroid is ALWAYS twice that of the distance to the midpoint, which would be on the side opposite of the chosen vertex. 

Let's call the identified side "B", the Centroid "A" and the Vertex "C"

Point B to point A is half the distance of point A to point C, as point B occurs on the opposite side of point C. 

This is the same for EVERY median. You could choose any line, and any vertex, and the answer would be the same. The side, if it's opposite of the vertex, is always half the distance to the centroid as the Vertex to the centroid is. 

Your answer A "Twice"

After a concert for 1,200 people, only 9 people said they would not go to see the band again. What percent of the people who wen
Ne4ueva [31]
To find what percent of 1,200 is 9, you need to divide 9 by 1,200 and then move the decimal two places to the right.

9 / 1,200 = 0.0075

Moving the decimal two places to the right gives us 0.75, so now you add a percent sign to the end.

.75% of people said they wouldn't go to see the band again. 

Hope I was able to help! :)
