Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood. How much wood did it take to cover the ramp, including the bottom?
Give an exact answer (do not round).

Step-by-step explanation:

Two triangular endsArea of one = 1/2 b * hb =1.2h =0.9Area = 1/2 * 1.2 * 0.9 =   0.54 sq metersArea of 2  = 2 * 0.54                                      1.08

Area bottom

L = 3.5 mw = 1.2Area = L * WArea = 3.5 * 1.2 Area =                                                              4.2

Area Back

L = 3.5W = 0.9Area = 3.5 * 0.9Area =                                                                     3.15

Area Slanted piece

L = 3.5w = 1.5Area = L * WArea = 3.5 * 1.5 =                                                   5.25

Total  = 5.25 + 3.15 + 4.2 + 1.08 =                               13.68                  

The person above me is perfectly right! Just keep in mind that questions like these are asking for surface area. Questions with “how much to cover.. “ and showing dimensions of a 3d figure are all about surface area.
