Answer:
SA = 189 cm^2
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
Answer:
200 [tex]cm^{2}[/tex]
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base(triangle)
LA = ph p = perimeter of base and h = distance between bases
LA = (5 + 5 + 6)11 = 176
B = bh/2 = 6(4)/2 = 12
SA = 176 + 2(12) = 176 + 24 = 200 [tex]cm^{2}[/tex]
