The area of each of the bases will be m2.

(1)(3) = 3

(1)(2) = 2

(2)(3) = 6

(3)(3) = 9

The area of the right and left lateral faces will be m2.

(1)(3) = 3

(1)(2) = 2

(2)(3) = 6

(3)(3) = 9

The area of the front and back lateral faces will be m2.

(1)(3) = 3

(1)(2) = 2

(2)(3) = 6

(3)(3) = 9

The lateral area of the prism will be m2.

Which equation could be used to find the surface area of the net of the triangular prism shown?

SA = (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

SA = (1/2) (5)(13) + (1/2) (5)(13) + (5)(2) + (13)(2) + (12)(2)

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

SA = (2)(5)(13) + (5)(2) + (13)(2) + (12)(2)

A = ft2

point D

point B

line CE

line DB

There are two bases, so total base area is ft2.

Point is not on plane P.

The lateral area is: A = (12)(3) + 12(5) + 12(4)A = ft2

and intersect at point .

The total surface area is ft2.
