Answer:

72 yd²

Explanation:

From the question,

Applying

A = Lb+Lw+Lh............... Equation 1

Where A = surface area of the three triangular prism.

From the question,

Given: L = 6 yd, b = 4 yd, w = 5 yd, h = 3 yd

Substitute these values into equation 1

A = (6*4)+(6*5)+(6*3)

A = 24+30+18

A = 72 yd²

Hence the right option is 72 yd²
