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 ![8:1](https://tex.z-dn.net/?f=8%3A1)
We know that 36<38<64
so sqrt36 < sqrt 38 < sqrt 64 it is equivalent to 6< sqrt38 < 8
since 38 is closer to 36 than it is to 64, so 6 is <span>approximate the square root of 38 as a whole number</span>
