Answer: 16 would be the answer. Just do 2 times 8 without the 2 00's and you get 16.

Answer:
the sum is -4
Step-by-step explanation:
Answer:
Lateral areas have ratio of 4:1
Volumes have ratio of 8:1
Step-by-step explanation:
There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of , the ratio of any surface area type measure is always this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of .
Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of which if you simplify it, it is , which is . The ratio of the heights are .
Now we can apply those rules to this ratio, the ratio of lateral areas would then be , which is . the ratio of volumes would be , which is
