one hundred fifty square feet

two hundred square feet

Answer 1

It is :
\[\frac{1000-500}{4}\text{ feet}\]

Answer 2

125?

Answer 3

total surface Area is 1000
you're given the squarish bottom, which is 500
there are 4 triangular faces, see above
so 1000 - 500 gives you the total for all 4 triangular faces
divide that by 4 faces, and you'd get 1 face Area
