Each of the small 12 identical blocks has dimensions 4 by 5 by 7 inches.
Together they form a larger block of:
width w=5 in
length l = 7 in+7 in+7 in = 21 in
height h = 4 in + 4 in + 4 in + 4 in=16 in
The total area of the block is:
(front face+back face)+("floor" face + "ceiling" face) + 2 side faces
=
16 * 21 + 16*21 + 5*21+ 5*21 + 5*16+5*16 (square inches)
=
336+336+105+105+80+80 (square inches)
= 672+210+160 (square inches)
=1,042 square inches
Answer: 1,042 square inches

PLEASE GIVE ME BRAINLEST I WORK HARD
If I was solving this, which I suppose I am, my first step would be the clear the fractions by multiplying both sides by <em>a</em>.
That's there, first choice, SELECT IT
Then I'd bring the 5 to the other side;
Not among the choices.
Then I'd attempt to factor, looking for a pair that multiplies to 5 and adds to 8; no joy there.

All the other choices have nice rational answers so can't be right.
First choice only
