Answer:
860.55 mm²
Explanation:
The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):
S= 6*b*(a+h)
where b = is the side of the base, a is the apothem length, and h = the height
S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm
Could have also have used another formula without the apothem:
S =3 * √3 * b² + 6 * b * h
S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55 + 528 = 860.55 sq mm
a); and c). During Chandragupta II reign, great impulse was given to arts and science. One of the main scholars of the time was Aryabhata, who came up with the concept of zero and discovered the ratio of pi. He also worked in demonstrating that the earth moves around the sun instead of otherwise.
