Answer:
Step-by-step explanation:
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh
Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24
The slant height is 8 inches.

-------------------------------------------------
(sqrt 9)^2 +5
Apply radical rule:
(9^1/2)2
Apply exponent rule:
9^1/2*2
1/2* 2= 1
=9
9+5= 14
Your Answer Is 14
