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:

Answer:
52 times 12 = 624
Step-by-step explanation:
364 divided 7 = 52
52 times 12 = 624
Answer:
13
Step-by-step explanation:
to round to nearest whole number if its .5 or above you go up 1. If it's .4 or below you go down 1.
2.414=2
8.160=8
2.621=3
add
2+8+3=13
if you just added the decimals you would get: 13.195. (This shows you have a good estimate.)
