Here's the answers I got. Sorry super busy at school ahh
Answer:
Correct group: fourth image
Surface area = 32 in2
Step-by-step explanation:
The dimensions required is 2 x 3 x 2, so in one dimension we need 2 cubes, in a second dimension we need 3 cubes, and in the third dimension we need 3 cubes.
In the first image, we have a 2 x 3 x 3 prism.
In the second image (to the right of the first one), we have a 2 x 4 x 1 prism.
In the third image (below the first one), we have a 3 x 4 x 1 prism.
In the fourth image, we have a 2 x 3 x 2 prism, so this is the correct option.
The surface area os this prism is 2*(2*2) + 2*(2*3) + 2*(2*3) = 8 + 12 + 12 = 32 in2
