Answer:
18/40
Step-by-step explanation:
1. Find a common denominator
8, 16, 24, 32, 40
5, 10, 15, 20, 25, 30, 35, 40
2/8 times 5= 10/40
1/5 times 8= 8/40
10/40 plus 8/40= 18/40
Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. 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.
