Step 1: Identify the given values. The problem states that a piece of stone "weighs 15kg". In physics, "weight" is a force, but when given in kilograms, it refers to the mass of the object. The volume is given as 40 m^3. Mass (m) = 15 kg Volume (V) = 40 m^3 Step 2: Recall the formula for density. Density () is defined as mass per unit volume. = (m)/(V) Step 3: Substitute the given values into the density formula and calculate. = 15 kg40 m^3 = 0.375 kg/m^3 Step 4: Compare the calculated density with the given options. The calculated density is 0.375 kg/m^3, which matches option A. The final answer is A. 0.375 kg/m^3. That's 2 down. 3 left today — send the next one.
