Answer:

  x^2(x + 2)/3 cubic inches

Step-by-step explanation:

The area of the square base is ...

  B = x^2

The volume is given by ...

  V = (1/3)Bh

where h represents the height, and B is the area of the base.

Using x+2 for the height, the volume of the pyramid is

  V = (1/3)(x^2)(x +2)

  V = x^2(x +2)/3 . . . cubic inches

The length of AE is 18in

Explanation:

From the figure, we can see that the two triangles ΔAED and ΔACB are similar. Thus, the legs of the triangle are proportional to each other.

Thus, we have,

\frac{EC}{DB} =\frac{AE}{AD}

Substituting the values of the sides from the image, we get,

\frac{3}{1} =\frac{AE}{6}

Multiplying both sides of the equation by 6, we get,

6(3)=AE

Multiplying, we have,

18=AE

Thus, the length of AE is 18in
