Find the total surface area ofa) a regular dodecahedron with each face having an area of 6.5 in².b) a regular tetrahedron with each edge measuring 4 cm.

To determine

(a)

To find:

The total surface area of regular dodecahedron.

Explanation

Given:

Regular dodecahedron with each faces having an area of 6.5 in².

Calculation:

Let us consider the regular dodecahedron figure.

A regular dodecahedron has twelve faces that are congruent with pentagons.

Regular dodecahedron with each faces having an area of 6.5 in².

The total surface area of regular dodecahedron is,

S=126

To determine

(b)

To find:

The total surface area of regular tetrahedron.
