Answer:
The surface area of a solid object is a measure of the total area. Find the area of all the sides and add them up.
Area of rectangles:
40+40+16+16= 112
split the pentagon so they will be a reactangle and a triangle.
6-2=4. The height of the triangle is 4.
3+3=6, 6*2=12. 12 is the area of the mini rectangles, 12*2=24. 24 is the total area for both the mini rectangles.
Area of the triangle is 12.
Add them all up:
112+12+24= 148
148
