Answer 2

Answer:

So we are given the length, width, and height and we are also told that we need to find the surface area.  The formula to finding the surface area of a rectangular prism is $S=2(w*h+l*w+l*h)$

We just plug in the values and solve

$S = 2(9\ in * 3.5\ in+6\ in * 9\ in + 6\ in * 3.5\ in)$

$S = 2(31.5\ in^2 + 54\ in^2+21\ in^2)$

$S = 2(106.5\ in^2)$

$S = 213\ in^2$

Hope this helps!  Let me know if you have any questions
