Answer:
volume = x(x + 2)(x - 1)
soil = 30 ft³
Step-by-step 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
