Answer:
1. For a cube, volume = ![edge^{3}](https://tex.z-dn.net/?f=edge%5E%7B3%7D)
2.
= edge
3. Volume of the cube = 216 so, the edge =
= 6
4. 1st blank = 6
2nd blank = 6
3rd blank = 216
4th blank = 216
5. 6 is the edge
6. As the room is a square and we have to find the side
Area = 121
Edge =
= 11
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Because when multiplying you add the number of variables, and there are 3 X's so it would be 6x with an exponent of 3
STU + STR = 180
8x + STR = 180 [ STU = 8x ]
STR = 180 - 8x
STR = SRT [ RS ≈ ST ]
Now, In ΔSRT,
we have, RST = 7x - 54, STR = SRT = 180-8x
Their sum is 180, as it constitutes a triangle.
7x-54 + 2(180-8x) = 180
7x - 54 + 360 - 16x = 180
306 - 9x = 180
9x = 306 - 180
9x = 306 - 180
x = 126/9
x = 14
So, option A is your answer.
Hope this helps!
