helllooo!! i need help with my assesment.
1: find the surface area of the rectangluar prism.
3in 2in 4in
a:60in
b:84in
c:26in
d:52in
2: a cube has a side length of x feet. which expression represents the surface area of the cube?
a: 4x square units
b: 24x sqaure units
c: x(2) square units
d: 6x(2) square units
i think its c and a but i dont know. someone please help correct meeeee. thanks
I did the quick check and the answers are
1. D
2. D
3. A
4. C
I got 100%! Trust me I'm right. Hope this helps cas these answers are hard to find so yea good luck!
Are you kidding me? I've been trying to find these answers for hours! And only one person said something?! They don't even have the answers! I'm tired of this!
somebody is right thank you i got 100%
"Somebody" is correct, thanks!
Hello! I'd be happy to help you with your assessment. Let's break down each question and go through the steps to find the correct answer.
1. To find the surface area of a rectangular prism, we need to add up the areas of all six faces. The formula for the surface area of a rectangular prism is:
SA = 2lw + 2lh + 2wh,
where l, w, and h represent the length, width, and height of the prism, respectively.
Given that the dimensions of the rectangular prism are 3in, 2in, and 4in, we can substitute these values into the formula:
SA = 2(3)(2) + 2(3)(4) + 2(2)(4) = 12 + 24 + 16 = 52in.
Therefore, the correct answer for the surface area of the rectangular prism is d: 52in.
2. The surface area of a cube is found by adding up the areas of all six faces, each face being a square with side length 'x'. Since a cube has all sides equal in length, we can represent the surface area as:
SA = 6x^2,
where x is the side length of the cube.
Looking at the answer choices, we can see that option d: 6x^2 square units matches the correct expression for the surface area of a cube.
So, the correct answer for the surface area of the cube is d: 6x^2 square units.
I hope this helps! Let me know if you have any other questions or need further clarification.
#1 You have three pairs of rectangular faces.
I'm sure you know how to find the area of a rectangle, so ...
#2 not C. x^2 is the area of one of the six faces.
So, care to change your answer?
