Answer:
Volume of figure 1 is 135
Volume of figure 2 is 108
Total Volume:243
Measure of side A is 8cm
Voume=6*7*3=126
Volume=8*3*3=72
Step-by-step explanation:
1.5*9*3=135
2.9*4*3=108
3.108+135=243
The opposite of -48 is positive 48, Written as just 48.
The answer is 5x + 76y
There is no complete standard form because there is no value for x or y given.
Answer:
<h2>The right answer is 415.4 cubic feet.</h2>
Step-by-step explanation:
As you can observe in the image attached, the composite figure is formed by a square prism and a pyramid on top.
We need to find the volum of each part separately.
<h3> Square prism.</h3>

<h3>Square pyramid.</h3>
First, we need to find the height of the pyramid. We already know the height of each triangular face of the pyramid, which divides equally the side.
Let's use Pythagorean's Theorem to find the height of the pyramid.

The height is 4.3 feet, approximately.
Now, we find the volume of the pyramid

The sum of both figures represents the total volume of the composite figure

Therefore, the right answer is 415.4 cubic feet.
First symmetrically cut the pentagon to get 5 pieces. (So that you will get the idea that this polygon is divided into 5 triangles)
Then find the area of one of the triangles:
Area of Triangle = 
A =
× 4 × 10
A = 20 m²
To find the area of the whole pentagon shape:
A = 20 × 5 = 100 m²
