Find the surface area

556 I think?

Step-by-step explanation:

well first you have to layer out all the squares so overall the equation would be 2(4*10)+2(170*10)+2(4*17)

which answers to 556

Answer = 556

Step-by-step explanation:

To find the surface area you have to find the area of each rectangle in the figure. Since you know the side lengths of them find the area of each rectangle. Area = L * W, so first count how many rectangles you have and if they have the same shape to another rectangle in the figure. You should know there are 6 rectangles in the shape and some rectangles ahve the same shape.

Steps:

First - 4 * 10  = 40

Second - 17 * 4 = 68

Third - 17 * 10 = 170

Fourth - 4 * 10 = 40

Fifth - 17 * 4 = 68

Sixth - 17 *10 = 170

40 + 40 + 68 + 68 + 170 + 170 = 556
