Answer:
1,800 ft^3
Step-by-step explanation:
Let's assume it is a swimming pool the Person wants.
The shape of the pool is a box. It has a rectangular surface (25' x 18') and a depth of 4'.
The volume (V) of a box is the product of Length x Width x Depth.
V = L*W*D
V (ft^3) = (25')*(18')*(4')
Vol = 1,800 ft^3
