1. To find the Volume of the rectangular prism, we use the formula V = l x w x h.
V = 5 x 1 x 3.5
V = 17.5
2. To find the Surface Area of the rectangular prism, we find the area of each of the six sides and add them together.
Surface Area = 2lw + 2lh + 2wh
Surface Area = 2(5)(1) + 2(5)(3.5) + 2(1)(3.5)
Surface Area = 10 + 35 + 7
Surface Area = 52
If you wanted to know how much water this rectangular prism could hold inside of it, you would use the Volume measurement, which in this case is 17.5 cubic units.
