Gavin Reeps a gift box in the shape of a triangular prism. The figure below shows a net for the gift box 15 m 14 m, 14 m 7 m 15.65 m 15.65 m how much wrapping paper did he use in square meters?
To calculate the total surface area of the net for the triangular prism, we need to find the area of each of the 5 faces and then add them up.
Face 1: 15m x 14m = 210 sq. meters
Face 2: 14m x 7m = 98 sq. meters
Face 3: 15.65m x 15.65m = 244.22 sq. meters
Face 4: 15m x 15.65m = 234.75 sq. meters
Face 5: 15m x 15.65m = 234.75 sq. meters
Total surface area = 210 + 98 + 244.22 + 234.75 + 234.75 = 1022.72 sq. meters
So, Gavin used 1022.72 square meters of wrapping paper for the gift box in the shape of a triangular prism.
