Answer:
The lateral surface area is 84 cm^2
Step-by-step explanation:
The rectangular prism is a geometric figure that has rectangles at each of it's faces. The lateral surface is formed by four rectangles, the ones formed by the length and the height and the ones formed by the width and the height. So in order to calculate the area of this surface we need to calculate the area of these rectangles and sum it. We have:
A_lateral = 2*width*height + 2*length*height
A_lateral = 2*6*3 + 2*8*3 = 36 + 48 = 84 cm ^2
So the lateral surface area is 84 cm^2
So what I would do is first multiply the mean by 4 and that is the total u need, 146.5, to have a mean of 36 and 5/8. Next I add the lengths given, which is 110.625, and then I would subtract it from 146.5 which is 35.875 which is 35 and 7/8. You can also check the answer by finding the mean of the 4 numbers and determining if it comes out to 36 and 5/8. The answer is C. Hope this helps!
I believe the correct answer from the choices listed above is the first option. The equation that can be used to solve the problem would be x + (x + 9) = 47.
<span>The sum of two numbers is 47. ---> x + y = 47 where x is the smaller number and y is the larger.
</span><span>The greater number is 9 more than the smaller number. -----> y = x + 9
x + ( x + 9 ) = 47</span>
Since we know that a square has all equal sides, we can simply divide the perimeter by 4 to get each side length.

Using the information above, we can see that each side is
3x+13 units.
