Answer 1

To find the surface area of the prism, we will consider the areas of each part of the net

For part A

Area of A = L x B = 29 x 5 = 145

Area of B = L X B = 29 x 13 = 377

Area of C = L x B = 29 x 12 =348

Area of D = 1/2 x H X B = 1/2 x 12 x 5 = 30

Area of E = 1/2 x H x B = 1/2 x 12 x 5 = 30

Total Area = 145 + 377 + 348 + 30 + 30
