The display after stacking of 6 layers of cube is 30 inches high.
Step-by-step explanation:
The volume of cubic box used by Abbey= 125 inch³
Total no of layer he has in display= 6
Height of the display-
We know that the volume of the cube is a³
Where a is the side of the cube
Hence to find the side of the cubic box we need to find the cube root of the volume i.e. ∛125
Hence the side of each cube is 5 inch. Since all the sides for cube are equal hence the height would also be 5 inch
The total height of the display would be 6*5= 30 inches
At D point in the bottom then up and to the right upper corner to Letter B
Answer:
11
Step-by-step explanation:
1/3 nr^2h = volume of a cone
1/3 x 22/7 x 14 x r^2 = 440
r^2 = 440 x 3 x 7/22 x 1/14
r^2 = 30
r = 30
r = 5
The answer is <span>A –x^2 + 3x + 15
</span>
3x² + 6 – 2x + 5x – 4x²<span> + 9
Rearrange it:
</span>3x² + 6 – 2x + 5x – 4x² + 9
= 3x² - 4x² - 2x + 5x + 6 + 9
= -x² + 3x + 15
