Question

Find the surface area of the figure below.​

Answer 1

696.8 mm^2

Explanation:

Well first lets find the bottom part of the square first.

13*13= 169

Thats the floor

13*5= 65

Thats 1 of the sides

there are 4 sides

65*4= 260

260+169= 429

Now find the triangle

(13*10.3) / 2

You’d get 66.95

66.95 *4 since there are 4 sides

You’d get 267.80

267.8+429= 696.8
