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?

Answer 1

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.
