Marissa needs to paint all the faces and the base of a model pyramid she made for her history project. the dimensions of the pyramid are shown here. what is the total surface area of the pyramid? 140 in2 180 in2 240 in2 260 in2

So first off we have the formula for the surface area A+1/2*p*s first we multiply 1/2*40(perimeter of base) to get 20 then multiply by 8 to get 160 then add 100(which is the area of base)  so final answer is 260 hope this helps sorry it took me a while.
