There will be 4 rows and 3 in each row. one more cube will be placed at the bottom.
hope it helps!
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
If the pieces are cut in the ratio <span>3:5:7</span>, the proportion of each piece to the whole (represented by <span>3+5+7=15</span>) is:
<span><span>3/15</span>:<span>5/15</span>:<span>7/15</span></span>
First, convert the inches to feet also:
1 foot equals to 12 inches.
So 9 inches <span>=<span>9/12</span>×1=0.75</span> feet.
Thus, 33 feet and 9 inches equal <span>33+0.75=33.75</span> feet.
So,
<span>P=<span>3/15</span>×33.75=6.75</span> feet.
<span>Q=<span>5/15</span>×33.75=11.25</span> feet.
<span>R=<span>7/15</span>×33.75=15.75</span> feet.
You can check that these answers are correct by adding up the different pieces: <span>6.75+11.25+15.75=<span>33.75</span></span>
