Question

Find the surface area​

Answer 1

The surface area of the hexagonal pyramid is 313.13 square inches.

Explanation:

Hexagonal pyramid,

Surface Area = Area of hexagon base + areas of six triangles

b = 6

h = 12.2 (height of the triangle)

A =
`(3√(3) )/(2)b + 6((1)/(2) bh)`

A =
`(3√(3) )/(2)b +3bh`

A =
`(3√(3) )/(2)6 +3*6*12.2\`

A = 93.53 + 219.6

A = 313.13 square inches
