Calculate the Volume and Surface Area of a Square Pyramid Which expression best shows how to find the surface area of this pyramid?

(30*20)/2 + (30*20)/2 + (30*20)/2+ (30*20)/2 + 30*30

(30*25)/2 + (30*25)/2 + (30*25)/2+(30*25)/2 + 30*30

(30*20) + (30*20) + (30*20)+(30*20) + 30*30

30*30 + 30*30+20*20+ 25*25+20*20 ​

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
