Below are sample questions representative of the exercises included on this worksheet and related 8.148 Using Nets to Find Surface Area skill assessments:

Problem 1Difficulty: Hard
The six faces of a box net are labeled 26, 26, 18, 18, 14, and 14 square feet. What is the total outer area when the box is folded?
Solution & Explanation:Surface area is the sum of all face areas in the net: 26 + 26 + 18 + 18 + 14 + 14 = 116. So the surface area is 116 square feet.
Problem 2Difficulty: Hard
A right triangular prism is unfolded into a net. The triangular bases each have area 96 square centimeters, and the three rectangles have areas 42, 56, and 70 square centimeters. What is the surface area?
Solution & Explanation:Add both triangular bases and the three rectangles: 2(96) + 42 + 56 + 70 = 360. So the surface area is 360 square centimeters.
Problem 3Difficulty: Hard
The net of a heptagonal prism includes two polygon bases, each 19 square yards, plus rectangles whose areas are 14, 14, 14, 14, 14, 14, and 14 square yards. How many square yards are in the full surface area?
Solution & Explanation:Add the two congruent bases and all side rectangles: 2(19) + 14 + 14 + 14 + 14 + 14 + 14 + 14 = 136. So the surface area is 136 square yards.
