A. Draw the cross section that is formed when the pyramid is sliced vertically through its vertex and its right face, perpendicular to its base. b. What is the area of this cross section?

i think it would be 42cm

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
