To find volume you multiply all three dimensions by one another. We can approximate this by multiplying the smaller ones first.
12*4=48 Now multiply 48 by 10.
48*10=480 We still have 7 to deal with, so we can multiply 48 by 2 and then by 5.
48*5=240
48*2=96
Now add the three together.
480+240+96=816.
Your answer is 816.
The value of Sin(a) suppose that Cos B = 0.68 in which case, a + B = 90° is; 0.68.
<h3>Trigonometry</h3>
First, when we have two angles, whose sum equals, 90°.
In essence, Since the algebraic sum of angles A and B is 90°;
By trigonometric identity;
Where; (90 - A) = B.
Therefore; Sin A = Cos B = 0.68.

Answer:
14th term of geometric sequence 7, 28, 112 is 469762048
Step-by-step explanation:
Geometric sequence : 7, 28, 112, .....
First term = a = 7
Common ratio = r =![\frac{a_2}{a_1}=\frac{a_3}{a_2}](https://tex.z-dn.net/?f=%5Cfrac%7Ba_2%7D%7Ba_1%7D%3D%5Cfrac%7Ba_3%7D%7Ba_2%7D)
Common ratio = r =![\frac{28}{7}=\frac{112}{28}=4](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B7%7D%3D%5Cfrac%7B112%7D%7B28%7D%3D4)
Formula of nth term =![a_n=ar^{n-1}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn-1%7D)
Substitute n = 14
So,![a_{14}=7(4)^{14-1}](https://tex.z-dn.net/?f=a_%7B14%7D%3D7%284%29%5E%7B14-1%7D)
![a_{14}=469762048](https://tex.z-dn.net/?f=a_%7B14%7D%3D469762048)
Hence the 14th term of geometric sequence 7, 28, 112 is 469762048
