Find the surface area of a square pyramid with side length 3 cm and slant height 6

cm.

45

Step-by-step explanation:

the formula is (P x slant height over 2) + B

P = perimeter of the base

B = area of the base

P = 3+3+3+3 P=12

B=3x3 B = 9

12 x 6 = 72 72 divided by 2 = 36 36 + 9 = 45

the surface area of your triangle is 45 cm squared

The answer is 46.10 just look it up
