Answer:
<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>
Step-by-step explanation:
To find the mass in kg we must first convert the density from g/cm³ to kg/m³
That's 7.5 g/cm³ = 7500kg/m³
Density = mass / volume
Volume of block = 1.5 × 0.4 × 0.25
= 0.15m³
mass = Density × volume
= 7500 × 0.15
<h3>= 1125 Kg</h3>
Hope this helps you

Answer:
steps below
Step-by-step explanation:
f(x) = x + 5
g(x) = x - 4
f(g(x)) = f(x-4) = (x-4) + 5
 
        
             
        
        
        
Answer:
24
Step-by-step explanation:
Area of the kitchen = Area small rectangle + area large rectangle + area triangle
Area small rectangle = (8-4)*1.5
Area large rectangle = (8-4)* 3
Area triangle = (1/2)*base*height = (1/2)*4*3
Area of the kitchen = (8-4)*1.5 +  (8-4)* 3 + (1/2)*4*3 = 24 cm²
