Answer:
120 cm²
Step-by-step explanation:
Applying,
A = Ph................... Equation 1
Where A = Literal Area of the triangular prism, P = Perimeter of the base, h = height.
But,
P = a+b+c............... Equation 2
Where a, b, c represent the three sides of the triangular base
Therefore,
A = h(a+b+c)............... Equation 3
From the question,
Given: h = 8 cm, a = 4 cm, b = 5 cm, c = 6 cm
Substitute these values into equation 3
A = 8(4+5+6)
A = 8(15)
A = 120 cm²
