No, it does not.
In general, surface area is the sum of the areas of each face of a prism. In a rectangular prism, we have length, width, and height.
The area of the bottom of the prism and the top of the prism is the same, and can be represented as l*w. This means that together, it is 2lw.
The area of the left and right faces of the prism is the same, and can be represented as l*h. This means that together, it is 2lh.
The area of the front and back faces of the prism is the same, and can be represented as w*h. This means that together, it is 2wh.
This gives us the equation
SA = 2lw+2lh+2wh
If we double the length and width, making them each 2l, we then have:
SA = 2(2l*2w) + 2(2l*h) + 2(2w*h)
= 2(4lw) + 4lh + 4wh
= 8lw + 4lh + 4wh
If the surface area had been doubled, we would expect
4lw + 4lh + 4wh
No, it is not doubled.

Hello from MrBillDoesMath!
Answer:
d>4
Discussion:
I understand the question is asking us to solve for "d" in the inequality:
d + 2 > 6 => subtract 2 from both sides
d + 2 -2 > 6 - 2 => as 2 - 2 = 0
d > 6 -2 = 4
If I have misunderstood the question, please tell me.
Thank you,
MrB

Answer:
x = 32
Step-by-step explanation:
(2x + 60) + (3x - 40) = 180 because they are supplementary angles
5x + 20 = 180
5x = 160
x = 32
