Question 737592: "You are painting the outside of a jewelry box including the bottom. To find the surface area (S.A) of the jewelry box, you can use the formula S.A = 2wl + 2lh + 2wh, where L is length, W is width, and H is height. What is the surface area of the jewelry box in terms of x."
L = 2x+5
W= x
H= x+3
Thank you so much!! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! we are given the following formula
S.A = 2wl + 2lh + 2wh where
L = 2x+5
W= x
H= x+3
substituting in the formula
S.A. = 2x*(2x+5) + 2(2x+5)(x+3) + 2x(x+3)
S.A. = 4x^2+10x+2(2x^2+11x+15)+2x^2+6x
S.A. = 4x^2+10x+4x^2+22x+30+2x^2+6x
combining like terms
S.A. = 10x^2+38x+30
