Find the total area of the four walls of a room 12 m long, 10 m wide and 4 m high.
Radda [10]

Answer:

<h2>416m^2</h2>

Step-by-step explanation:

<h3>Area = Length * Width</h3><h3>Volume = Length * Width * Height</h3>

<h3>As we all can see,from the question we were given the parameters for calculating volume instead of the ones for calculating "area"</h3>

<h3>But from the the parameters, we can calculate for the total surface area</h3>

<h3>Floor = 12m ×10m = 120m^2</h3>

<h3>Roof = 12m × 10m = 120m^2</h3>

<h3>Front and back walls (x2) = 10m × 4m ×2 = 80m^2</h3>

<h3>Side walls (x2) = 12m × 4m × 2 = 96m^2</h3><h3>Total surface area</h3>

<h3>= 120m^2 + 120m^2 + 80m^2 + 96m^2</h3>

<h3>= 416 m^2</h3>
