do you know formula for ..?
jhonyy9 (jhonyy9):
or not ?

so than this is
V = area of base time H divide by 3
ok ?
OpenStudy (anonymous):
okay

the base is a square so area of a square = ?
OpenStudy (anonymous):
A=s^2?
jhonyy9 (jhonyy9):
yes,right
OpenStudy (anonymous):
okay but I`m trying to find the volume of the square pyramid? I`m so confused
jhonyy9 (jhonyy9):
ok
but for volum of it first you need calcule area of base

check formula what i have wrote little above
OpenStudy (anonymous):
okay A= s^2 so would that be 15^2? which equals 225
jhonyy9 (jhonyy9):
area of base will be 11 squared
OpenStudy (anonymous):
okay so 121 then what formula do I use to find volume? area of base which is 121 times 15 divided by three?
jhonyy9 (jhonyy9):
yes eaxctly
