Answer:
It's 51 square inches. You can multiply 12x8 and subtract 9x5 from that.
The rule says that:
each small angle has a small side
then the angle in front of BC is the smallest
in front of CA is the middle
in front of AB is the largest
I hope this helped and Good luck
thank you
The selected answer is correct
Answer:
900 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon can be found by
(n-2)*180 where n is the number of sides
This figure has 7 sides
(7-2)*180
5*180
900
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of

if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so

this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is

and the last one is KYXLMJ (the top "triangle")
the volume is

so now add them up
and has to equal 444

and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes

3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D
