The surface area of a rectangular prism is calculated by finding the sum of the areas of all six sides.
Surface Area = 2lw + 2lh + 2wh
Given:
l = 7 cm
w = 2 cm
h = 10 cm
Substitute the values into the formula:
Surface Area = 2(7)(2) + 2(7)(10) + 2(2)(10)
Surface Area = 28 + 140 + 40
Surface Area = 208 cm^2
Therefore, the surface area of the rectangular prism is 208 cm^2.
Answer: 208 cm.^2
