Answer:
4,243 cm^3
Step-by-step explanation:
In this question, we are asked to calculate the amount of gift wrap needed to cover the box.
This is indirectly telling us to calculate the volume of the triangular prism.
Mathematically, the area of a triangular prism is the area of the base multiplied. y the height.
Area of the base is 1/2 * 12 * 10.4 = 62.4 cm^2
The volume is thus 62.4 * 68 = 4,243.2 cm^3

The solution is that x = 26 and y = 9.
In order to find these, we need to note that since the two angles involving x's make a straight line, then they must equal 180 degrees. So we can add them together and set them equal to solve for x.
5x - 17 + 3x - 11 = 180 ----> combine like terms
8x - 28 = 180 ----> add 28 to both sides
8x = 208 -----> divide by 8
x = 26
Now that we have the value of x, we can find the value of the 3x - 11 term. That along with the right angle and the 2y + 5 angle combine to make another straight line. So we can solve by setting that equal to 180 as well.
3x - 11 + 90 + 2y + 5 = 180 ------> Combine like terms
3x + 2y + 84 = 180 -----> Put 26 in for x.
3(26) + 2y + 84 = 180 -----> Multiply
78 + 2y + 84 = 180 ------> Combine like terms again
2y + 162 = 180 ------> Subtract 162 from both sides
2y = 18 -----> Divide by 2
y = 9
