Surface area = 2(wl + hl + hw) = 2wl + 2hl + 2hw
Conditions:
base length is shrunk by a factor of 2/3
width is quadrupled
height is cut in half.
l ⇒ 2l/3 w ⇒ 4w ; h ⇒ h/2
SA = <span>2wl + 2hl + 2hw
</span>SA = 2(4w)(2l/3) + 2(h/2)(2l/3) + 2(h/2)(4w)
SA = (16wl/3) + 4hl/6 + 8hw/2
Simplify:
SA = 16/3 wl + 2/3 hl + 4hw Choice C.

Step-by-step explanation:
In proving using the law of cosines, you need to consider these two key elements. The first element is a^2 + b^2 - 2abcosC and the second one is cosine^2 theta + sin^2 theta is equal to 1. Law of Cosines is derived from the Pythagorean Theorem
