Learn the difference and when to use each. article https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-geometry-topic/cc-6th-surface-area/v/surface-area-word-problem-example 2023-09-21T21:49:35.177342261Z Surface area word problem example Akira won a science fair and got a golden pyramid trophy. We want to find out how much gold foil was used. The trophy has a square base and four triangular faces. By calculating the area of these shapes, we can find the total surface area covered by the gold foil. video https://cdn.kastatic.org/ka_thumbnails_cache/f197e8ba-6c6d-454e-abb0-4e86e4a315d6_1280_720_base.png Surface area word problem example Akira won a science fair and got a golden pyramid trophy.
