Answer:
[tex]2304 \ in^3[/tex]
Step-by-step explanation:
Given the surface dimensions of the garden as 24 inches by 48 inches:
#Calculate surface area of the garden's top:
[tex]A=lw\\\\=48\times 24\\\\=1152 in^2[/tex]
Given the soil's thickness is 2 Inches, we multiply this thickness by the garden's surface area to get volume of soil used:
[tex]V=tA, t-thickness, A=Area=1152 \ in^2\\\\=2 \ in \times 1152\ in^2\\\\=2304 \ in^3[/tex]
Hence, the amount of soil used is 2304 cubic inches.
