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
Let my know of any questions.
