Answer:

166 in^2

Explanation:

I know, this isn't the best way but we can add up all the sides:

2(28+20+35) = 2(83) = 166 in^2

Hope this helped

Answer:

166

Explanation:

SA = 2lw** + 2lh +2hw

** It's 2 x l x w, not 21 x w (it looks like a 1, I know smhh)

l = 4

w = 7

h = 5

2*4*7 + 2*4*5 + 2*5*7 = 56 + 40 + 70

56 + 40 + 70 = 56 + 110

56 + 110 = 166
