Hello!
To find the surface area of a rectangular prism you use the equation
SA = 2(wl + wh + lh)
SA is surface area
w is width
l is length
h is height
Put in the values you know
SA = 2(4.5 * 16 + 4.5 * 29 + 16 * 29)
Multiply
SA = 2(72 + 130.5 + 464)
Add
SA = 2(666.5)
Multiply
SA = 1333
The answer is 1333 cm squared
Hope this helps!

x = -1²/₇ </h3>
Step-by-step explanation:
-(-10x - 8) = -(4x + 10)
10x + 8 = -4x - 10
-8 -8
10x = -4x - 18
+4x +4x
14x = -18
÷14 ÷14
x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇
I think you meant -(10x-8)=-(4x+10)
Then:
-(10x - 8) = -(4x + 10)
-10x + 8 = -4x - 10
-8 -8
-10x = -4x - 18
+4x +4x
-6x = -18
÷(-6) ÷(-6)
