Answer:
the amount of soil needed is[tex]90 in ^3[/tex]
Step-by-step explanation:
N/B: the width is 8 in
this problem bothers on the mensuration of solid shapes, rectangular prism
Given data
length l= 15 in
width w= 8 in
height h= 3/4 in
The amount of soil need in the flower box is equivalent to the volume of the box for the given data.
[tex]volume- of- soil= L*W*H\\\volume- of- soil= 15*8*(3/4)\\\volume- of- soil= \frac{360}{4} \\\volume- of- soil=90 in^3[/tex]
