Answer:
we know that
The volume of the prism is equal to
V=L*W*H
where
L is the length side of the base of the prism
W is the width side of the base of the prism
H is the height of the prism
In this problem we have
L=\frac{d-2}{3d-9}=\frac{d-2}{3(d-3)}
W=\frac{4}{d-4}
H=\frac{2d-6}{2d-4}=\frac{2(d-3)}{2(d-2)}=\frac{(d-3)}{(d-2)}
Substitute the values in the formula
V=\frac{d-2}{3(d-3)}*\frac{4}{d-4}*\frac{(d-3)}{(d-2)}=\frac{4}{3(d-4)}=\frac{4}{3d-12}
therefore
the answer is the option
4/3d-12

Answer:
1944 Inches Squared
Step-by-step explanation:
Surface area Formula for a Cube:

The "edge", which is also the side, is 18 inches.

Solve the formula.

The cube's surface area should be 1944 square inches.
Formula for surface area of a sphere of radius r is A = 4pi*r^2.
The same formula, for the case where the radius is 2.45 times greater, comes out to A = 4pi*[2.45r]^2.
Just find the ratio of
4pi*r^2 to 4pi*[2.45r]^2. It is 1/6.
