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 
Answer:
divide.
Step-by-step explanation:
Answer:
volume=12m
Step-by-step explanation:
width*length*height=volume
4m=width
3m=height
4m*3m=12m
12m=volume
Answer:
6450
Step-by-step explanation:
1kg = 1000g
6.45 x 1000 = 6450
