Answer:
a. A triangular prism
b. SA = bh + Pd
c. 144 cm²
Step-by-step explanation:
b. SA = bh + Pd where b is the base of the base triangle, is the height of the base triangle, P is the perimeter of the base triangle, and d is the depth of the triangle (the depth is perpendicular to the base triangle)
SA = bh + Pd
b = 4
h = 3
P = 3 + 4 + 5 = 12
d = 11, so
SA = 4(3) + 12(11) = 144
