Step-by-step explanation:
the volume of a rectangular block or tank is
length × width × height
so, it is like all regular 3D objects
base area × height.
so, we get
120 × 75 × 48 = 374,400 m³ = 3.744 × 10⁵ m³
why ?
374,400 = 374400 × 10⁰ = 37440 × 10¹ =
= 3744 × 10² = 374.4 × 10³ = 37.44 × 10⁴ =
= 3.744 × 10⁵
