If <span>∆QRS≅∆TUV, Their corresponding sides would be equal so,
QS = TV
5v + 3 = 6v - 9
6v - 5v = 3 + 9
v = 12
Now, QS = TV = 5(12) + 3 = 60 + 3 = 63
In short, Your Answer would be Option B
Hope this helps!</span>
Since 3 feet = 1 yard, Colin needs 3 cubes on each edge. (See picture below.)
In that picture, you'll also see that there are 9 cubes on one layer and there are three layers.
9x3 = 27
7/8 = 14*(1/16)
Maybe you're expecting
7/8 = 7*(1/8)
