Well, if one face has an area of 81 square centimeters, then that means that each side of the square is 9 centimeters. The formula to find volume is
, so 9^3 = 729.
In short, your answer would just be 729 centimeters

Answer:
67 1/2
Step-by-step explanation:
22 1/2*3
The coordinates of point D is (0, 7)
<h3><u>solution:</u></h3>
The midpoint M of CD has coordinates (2, 5)
Point C has coordinates (4, 3)
To find: coordinates of point D
The midpoint of line AB conatining points 
and 
is given as:
Here in this problem,
Midpoint (C, D) = (2, 5)
Subsituting the values in formula we get,
On comparing both the sides we get,
Thus the coordinates of point D is (0, 7)
X^2+4x-4=8
x^2+4x-4-8=0
x^2+4x-12=0
x^2+6x-2x-12=0
x(x+6)-2(x+6)=0
x+6=0 x-2=0
x=-6 x=2

It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.
