Solution Preview

To find out how many pounds of sand is required, we first need to compute the volume of sand for each of the cases.
The length and width of the tank is common for all cases. Only the height of the base varies.
Length of the tank (L) = 71 inches
Width of the tank (W) = 18 inches
Volume Calculations:
Case 1: 3 inch base of sand
Height of base (H) = 3 inches.
Volume of the sand in the fish tank (V) = Length x Width x Height
= 71 x 18 x 3
= 3834 cubic inches

Case 2: 4 inch base of ...
