Apackage is in the shape of a triangular prism. the bases are right triangles with perpendicular legs measuring 9 centimeters and 12 centimeters. the distance between the bases is 10 centimeters. what is the surface area of the triangular prism? square centimeters

468 square centimeters

Step-by-step explanation:

The surface area of each of the triangular base is

where a and b are the perpendicular legs of triangle (the triangular base must be right triangle)

⇒The surface area of each of the triangular base

The third side of triangular base =

Then the lateral areas of each rectangle of dimensions 10 × 9, 10 × 12, and 10 × 15.

Thus the total lateral area is

The total surface area is

for b its (t) and c its (d)
