Answer 1

volume = x(x + 2)(x - 1)

soil = 30 ft³

Explanation:

volume of a cuboid = width x length x height

• width = x ft
• length = (x + 2) ft
• height = (x - 1) ft

Substituting given values into the equation:

⇒ volume = x(x + 2)(x - 1)

If width = 3ft, then x = 3:

⇒ volume = 3(3 + 2)(3 - 1)

= 3(5)(2)

= 30 ft³
