Answer:
95
Step-by-step explanation:
I'm kinda just doing this for points now T_T
95 square units
Surface area of pyramid = 4(side area) + base
Solve for the base first.
Area of base = s*s = 5*5 = 25
Next solve for one of the sides.
Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5
Plug these back into our original equation.
Surface area of pyramid = 4(17.5) + 25
Surface area of pyramid = 70 + 25 = 95 square units
1.666666667
1/3 of 20 is 6.66666667
5-6.66666667 is -1.666666667
hope this helps :)
