Answer:
SURFACE AREA OF TRIANGULAR PRISM IS---
area of two triangles:
h = 4, b = 6
A = 1/2(b)(h) = 1/2(6)(4) = 12 sq. ft (area of one triangle)
two triangles, so 12 sq. ft + 12 sq. ft = 24 sq. ft
area of two equal rectangles:
l = 7, w = 5
A = (l)(w) = (7)(5) = 35 sq. ft (area of one rectangle)
two rectangles, so 35 sq. ft + 35 sq. ft = 70 sq. ft
area of one (bottom) rectangle:
l = 7, w = 6
A = (l)(w) = (7)(6) = 42 sq. ft
24 + 70 + 42 = 136 sq. ft
<h2>Answer: 136 sq. ft</h2>
