Given that the surface area of a rectangular prism is given by the formula sa = 2lw + 2lh + 2wh, what is the value of sa if h = 1 2 cm, l = 8 cm, and w = 6 cm?

The surface area of the rectangular prism is given by:

Where,

l: length

w: width

h: height

Therefore, substituting values we have:

Rewriting we have:

The value of the supercifial area is given by:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
