Step-by-step explanation:
The area of a regular octahedron is given by:
area = . Let a is the length of the edge (diagonal).
area =
Given that the diagonal of the octahedron is equal to height (h) of the tetrahedron i.e.
a = h, where h is the height of the tetrahedron and a is the diagonal of the octahedron. Let the edge of the tetrrahedron be e. To find the edge of the tetrahedron, we use:
The area of a tetrahedron is given by:
area = =
The ratio of area of regular octahedron to area tetrahedron regular is given as:
Ratio =
Answer:
43.2
Step-by-step explanation:
convert percentage (32%) by moving decimal to left 2 places = 0.32
135 * 0.32 = 43.2
