You can put this solution on YOUR website! A rectangular box with volume 18 cubic metres has a square base with side length x metres.
Express the surface area S of the box as a function of x.
:
The Volume of box with a square base: V = x^2 * h
x^2 * h = 18
h =
:
Surface area: S.A. = 2(L*W) + 2(L*h) + 2(W*h)
In this problem:
L & W = x; h =
we have
S.A. = 2x^2 + 4(x*)
S.A. = 2x^2 +
