Help me with this answer

9600

Step-by-step explanation:

To find the surface area, you need to find the area of all of the 2D shapes in the net of this cube. Since all of the squares are the same size, you multiply 40 x 40 x 6 because there are 6 sides.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
