Answer:
39364
Step-by-step explanation:
You can simplify the equation to make 4(1+3+9...) The nth term is therefore 
so u can substitute that into the equation so 4(
..). This would simplify to 4(
+
). By simplifying this, you can make it so 4(
) = 4(4+36+324+2916+6561) =39364
Answer:
Step-by-step explanation:
The octahedron is formed from 2 congruent square pyramids.
Since each die has the shape of an octahedron, we would determine its volume by applying the formula for determining the volume of an octahedron which is expressed as
Volume = (a³√2)/3
Where
a represents the length of each edge.
From the information given,
a = 1 cm
Therefore,
Volume = (1³√2)/3 = 0.471 cm³
1 hour = 60 mins = 3600 sec
-
6 sec = 1 flash
3600 sec = 3600 ÷ 6 = 600 flashes
-
Answer: 600 flashes
