5. Lateral Surface area is [unparseable or potentially dangerous latex formula], where l is the slant height. Volume is just regular height formula.

26. Ouch, sorry.

34. [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula].
[unparseable or potentially dangerous latex formula].

39. Case 1: red then black
[unparseable or potentially dangerous latex formula].
Case 2: black then red
[unparseable or potentially dangerous latex formula].
[unparseable or potentially dangerous latex formula].

40. Sorry, I do not know. I didn't get it when I attempted it on a test either.

44. You could do [unparseable or potentially dangerous latex formula], or just convert to base 10 then to base 8. 3+2+2 = 7.

45. Don't know a quick way for this one either.

number 40 its pretty easy in total their are [unparseable or potentially dangerous latex formula] total combos for three arrows to land, then, if you count, their is 8 ways for it to land in the wanted places so [unparseable or potentially dangerous latex formula] then take the odds finally gone to the library
