Answer:

Step-by-step explanation:

b- base of the triangle = 6

h - height of the triangle = 4

L = length of the rectangles = 7

s₁ = breadth of the base rectangle = 6

S₂ = breadth of the right rectangle = 5

s₃ = breadth of the left rectangle = 5

Surface area of the prism = bh + L*(s₁ + s₂ + s₃)

                                          = [ 6*4 ] + 7 * (6+5+5)

                                          = 24 + 7*16

                                          = 24 + 112

                                           = 136 square units
