Answer:
6 meters is missing length
Step-by-step explanation:
<em>The surface area of a prism is:</em>
<em>A = area of base</em>
<em>L = Lateral area</em>
<em />
<em>A + L = Surface area</em>
<em />
<em>Area of Base = 8x * 2(2 bases) = 16x</em>
<em />
<em>Lateral Area = (2x+16)6 = 12x+96</em>
<em />
<em>12x+96+16x = 264</em>
<em>28x + 96 = 264</em>
<em>28x = 168</em>
<em>x = 6</em>
