Answer:
1359.54m^3
Step-by-step explanation:
The formula for the volume of a triangular prism is:
1/2(
<em>b= base </em>
<em>l = length</em>
<em>h</em><em>= </em><em>height</em>
Step 1: Plug the numbers into the formula
1/2(12.6*13)*16.6
Step 2: Simplify
163.8*16.6
1359.54
Step 3: Add units
The units used in the question were in meters, so the answer is also in meters.
Volume is always cubed, so it would be to the third power...1359.54m^3
If this answer helped you, I would greatly appreciate if you gave me brainliest :D.
The area of Tinyville if the population of Tinyville is 405 Tinys while the population density of the Tinyville is 16.2 is 25 Acres.
<h3>What is Ratio?</h3>
A ratio shows us the number of times a number contains another number.
As it is given that the population density of Tinyville is 16.2 Tinys per acre, while the population of Tinyville is 405 Tinys. Therefore, the area of the Tinyville is the ratio of the population of Tinyville to the population density of the Tinyville.


Hence, the area of Tinyville if the population of Tinyville is 405 Tinys while the population density of the Tinyville is 16.2 is 25 Acres.

The bridge attached is drawn according to given dimensions, and it doesn't look right. Please double check the given dimensions.
Calculations:
Horizontal part of bottom chord below the 70 degree triangle
= 15.1*cos(70) = 5.16 (which is a major prt of the 6.3 units.
Height of vertical pieces DF and EH
= 15.1*sin(70) = 14.19
Note that structurally, DF and EH do not help in reducing stress on the bridge, since they are perpendicular to the bottom chord.
Therefore
angle B = atan(14.19/(6.3-5.16))=85.41 degrees
I believe the whole geometry does not look right, esthetically, and structurally, since the compression members are much longer than the tension members in the middle. (The vertical members carry no force.)
