So you don't need to find the surface area of the building?

anonymous · Answer

anonymous · Answer

he did find the surface area

anonymous · Answer

actually i found the volume!!!!! - i just noticed that - it would only be a surface area if one of the numbers was the number of walls!! - so embarassing!
can u check the question again jlastino!!

jlastino · Answer

haha.I think that was the volume. Anyways, i tried using the equation = 2lh +2wh

anonymous · Answer

for the area of the wall you just need w * h and then no. of walls in the building for total surface area

jlastino · Answer

(4wh/500) .Lol at my equation because 2lh would be the bases of the building (not the walls, of course). Thanks jimmy!
