Question

Please find the SURFACE are for this figure . Be geniune I will mark you the brainliest -.-

Answer 1

Answer:

576 ft^2

Step-by-step explanation:

The surface area of this 3D figure is the same thing as adding the surface areas of all the sides. This means that we first need to find the surface area of one of the rectangles.

Area of rectangle = length times width

Area of rectangle = 13 * 9

Area of rectangle = 117

Now, as there are 4 rectangles within this 3D figure, we multiply 117 by 4, to get 468. We must now figure out the area of the 2 other rectangles.

Area of rectangle = length times width

Area of rectangle = 9 * 6

Area of rectangle = 54

Now, as there are 2 of the other rectangles, we must multiply 54 by 2 to get 108. We can now add 468 and 108 to get 576 ft^2.
