Answer:
nope
Step-by-step explanation:
Volume of a cube = a^3
1st cube with edge of 8:
V= 8^3
V= 512 cubic inches
2nd cube
V = (2 X 8)^3
V= 4096 cubic inches 
If we multiply by 2 the 1st volume it is equal to 1024 cubic inches only, while the volume ogmf the 2nd cube is 4096
 
        
             
        
        
        
The formula for the volume of a triangular pyramid is:
V=1/3AH (where A=area of the base and H=height)
The formula for the volume of a triangular prism is:
V=AH (where A=area of the base and H=Height)
Since the base and the height are the same in this problem for both the prism and the pyramid, solving for the volume of the prism is simple.
Looking at the formulas, you'll see that the volume of the pyramid (assuming that both the height and the area of the base are the same) is 1/3 the volume of the prism.
V(pyramid)=1/3V(prism)
Now lets input the volume of the pyramid
26cm³=1/3 V(prism)
Divide both sides by 1/3
78cm³=V(prism)
Answer=78cm³
        
                    
             
        
        
        
This question has this set of answer choices:
a) when the plane cuts three faces of the cube, separating one corner from the others 
b) when the plane passes through a pair of vertices that do not share a common face
c) when the plane is perpendicular to the base and intersects two adjacent vertical faces
d) when the plane makes an acute angle to the base and intersects three vertical faces
e) not enough information to answer the question
The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others 
You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.
 
        
        
        
X = 42
x/3 - 4 = 10
 + 4 +4
x/3 = 14
•3 •3
x = 42
