Answer:
SA = 384 in ^2
Step-by-step explanation:
The surface area of a cube is given by
SA = 6 S ^2 where s is the side length
SA = 6 * (8) ^2
SA = 6 * 64
SA = 384 in ^2
The formula for finding the sum of the interior angles<span> of a </span>polygon<span> is the same, whether the </span>polygon<span> is regular or irregular. So you would use the </span>formula<span> (n-2) x 180, where n is the number of sides in the</span>polygon<span>. If you draw a diagonal in the square, that forms two triangles.</span>
W represents the weight of each book
2w + 4 = 18
2w = 18 - 4
2w = 14
w = 14/2
w = 7 oz <===
