Answer:
\(3\ bags\)
Step-by-step explanation:
we know that
The volume of the windows box is equal to
\(V=lwh\)
where
l is the length side of the box
w is the width side of the box
h is the height of the box
In this problem we have
\(l=5\ ft\)
\(w=6\ in\) ------> convert to feet ----->\(6/12=0.5\ ft\)
\(h=9\ in\) ------> convert to feet ----->\(9/12=0.75\ ft\)
substitute the values
\(V=5*0.5*0.75=1.875\ ft^{3}\)
Find how many bags of soil will Zen need to fill the window box completely
by proportion
\(\frac{1}{0.625}\frac{bag}{ft^{3}}=\frac{x}{1.875}\frac{bag}{ft^{3}}\)
\(x=1.875/0.625\\x= 3\ bags\)
