The height of Figure A is doubled to create Figure B. How will the surface area be affected? The surface area will remain the same.
The surface area will double.
The surface area of Figure B will be greater than the surface area of Figure A.
The surface area of Figure B will be less than the surface area of Figure A.

Step-by-step explanation:

Figure A = 52

Figure B = 92

So, the answer is C.

We can use this formula: A = 2(2wl + 2lh + 2hw) to find the surface area.

In figure B, 2 is the Length, 3 is the Width and 8 is the Height. According to the formula, this is what our problem will look like.

2· (3 · 2) + (8 · 2) + (8 · 3)

Let's solve for Figure B.

3 · 2 = 6

8 · 2 = 16

8 · 3 = 24

Now, add the answers up then multiply it by 2.

24 + 16 + 6 = 46 · 2 = 92

Like for Figure B, we can use this formula: A = 2(2wl + 2lh + 2hw) to find the surface area.

In figure B, 2 is the Length, 3 is the Width and 4 is the Height. According to the formula, this is what our problem will look like.

2· (3 · 2) + (8 · 2) + (4 · 3)

Let's solve for Figure B.

3 · 2 = 6

8 · 2 = 16

4 · 3 = 12

Notice that the measurements expect the height are the same.

Now, like we did on Figure A, add all then multiply by 2.

6 + 16 + 21 = 43 · 2 = 52
