find the surface area of a box of hieght h whose base dimensions are p and q, and that satisfies either one of the following conditions:

Question

a) the box is closed.
b) the box has an open top.
c) the box has an open top and a square base.

Answer 1

As = 2(L*W) + 2(L*h) + 2(W*h),

L = p units.
W = q units.
h = h units.

As = 2(p*q) + 2(p*h) + 2(q*h) = Surface
area.
The above Eq satisfies condition "a".
