Answer:

400 square inches

Explanation:

surface area= summation of area of all the faces the object has

out object has 2 triangular faces, and 3 rectangular faces

S.A = 2(0.5bh) + LW +LW+LW

= 2(0.5 x 8 x 15) + (15x7) + (17 x 7) + (7×8)

= 120+105+119+56

= 400 square inches

The surface area of the triangular prism is 400 square inches

Calculating the surface area of the triangular prism.

From the question, we have the following parameters that can be used in our computation:

The Triangular Prism.

The total area of the Triangular Prism is the sum of the individual shapes

So, we have

Surface area = 2 * triangle area + area of big rectangle

Using the above as a guide, we have the following:

Surface area = 2 * 1/2 * 8 * 15 + (8 + 17 + 15) * 7

Evaluate

Surface area = 400

Hence. the total area of the figure is 400 square inches
