Brick wall

What is the weight of a solid brick wall that is 30 cm wide, 4 m long, and 2 m high? The density of the brick is 1500 kg per cubic meter.

Final Answer:

m =  3600 kg

Step-by-step explanation:

$$\begin{gathered} a=30\text{cm}\to \text{m}=30:100\text{m}=0.3\text{m} \\ b=4\text{m} \\ c=2\text{m} \\ h=1500{\text{kg/m}}^3 \\ V=a\cdot b\cdot c=0.3\cdot 4\cdot 2=\frac{12}{5}=2.4 \\ m=h\cdot V=1500\cdot 2.4=3600\text{kg} \end{gathered}$$
