Answer:
To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
The correct answer is A and B because if you replace the m's with 4 than you do get the answer at the end of the equation. Hope this helps.
