Answer:
L = 2w
A = L*W
A = 2w*w
A = 2w^2

Given the question in the image, the following are the solution steps to answer the question
STEP 1: Write the general equation of an ellipse

STEP 2: Identify the parameters
the length of the major axis is 2a
the length of the minor axis is 2b

STEP 3: Get the equation of the ellipse

STEP 4: Pick the nearest equation from the options,
Hence, the equation of the ellipse in the image is given as:

OPTION A
So each dimention is 32 by 8 by 10
so the surface area=2 times(8 times 10)+(2 times (32 times 10))+(2 times (8 times 32))=2 times 80+2 times 320+2 times 256=1312
if halved
just divide each by 2
(2 times 4 times 5)+(2 times 16 times 5)+(2 times 4 times 16)=(2 times 20)+(2 times 80)+(2 times 64)=40+160+128=328
the new surface area is 328 mm^2
