Answer 1

The picture shown is a unfolded rectangular prism.

The formula to find the surface area of a rectangular prism is:

A = 2(WL+HL+HW)

(W = width, L = Length, H= Height)

So we would need to determine the Height, Length, and Width first, and then plug them into the formula and solve for the area.

In this case:
The height is: 4 cm 
The length is: 10.5 cm
The width is: 6.4 cm

Now that we have determined the height, length, and width, we simply plug them into the formula I showed earlier. 

In this case the answer would be 269.6.

D. 269.6
