| To calculate the value of the volume of the presented body, we apply the formula: V = Fa / (ρwater * g) = (Pair – Pwater) / (ρwater * g).
Constants and variables: Pair – weight in air (Pair = 26 kN = 26 * 10 ^ 3 N); Pwat – the weight of the represented body in water (Pwat = 16 kN = 16 * 10 ^ 3 N); ρwater – water density (ρwater = 1000 kg / m3); g – acceleration due to gravity (g ≈ 10 m / s2).
Let’s calculate: V = (Pair – Pwater) / (ρwater * g) = (26 * 10 ^ 3 – 16 * 10 ^ 3) / (1000 * 10) = 1 m3.
Answer: The volume of the presented body is 1 m3.
