A kitchen drawer has a Volume 1,125 cubic inches. The drawer is 15 inches long and 5 inches deep. What is the width of the drawe

Temka [501]

Answer:

The width of the drawer is $15\ in$

Step-by-step explanation:

we know that

The volume of the drawer is equal to

$V=LWH$

we have

$L=15\ in$

$H=5\ in$ -----> the deep of the drawer

$V=1,125\ in^{3}$

substitute the given values in the formula and solve for W

$1,125=(15)(W)(5)$

$1,125=(75)(W)$

$W=1,125/(75)$

$W=15\ in$
