Answer:
area = 779.4 cm²
Step-by-step explanation:
divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.
tan 60° = 15/x
1.7321 = 15/x
x = 8.66 (this is one-half of the base of the triangle)
base = 17.32 cm
area of one triangle = 1/2(17.32)(15) = 129.9 cm²
129.9(6) = 779.4 cm² (because 6 triangles make up the hexagon)
The answer to this question is
x = -15 + y
Surface Area of the Prism = (6x4) = 2(5x4) + 2(1/2x6x4)
Surface Area of the Prism = 24 + 40 + 24
Surface Area of the Prism =88 cm²
