Answer:
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
