Answer:
The sheet steel costed $22.41 per square meter
Step-by-step explanation:
<em>To find the cost per square units find the lateral area (they will made the walls only) of the rectangular prism and divide the cost of the steel sheet by it</em>
The formula of the lateral area of the rectangular prism is:
LA = perimeter of base × height
∵ The length of the base is 9 m
∵ The width of the base is 5 m
∵ The height of the prism is 7 m
- Find the perimeter of the base
∵ Perimeter of base = 2(length + width)
- Substitute the values of the length and the width
∴ Perimeter of base = 2(9 + 5) = 28 m
Now use the formula of the lateral area to get it
∵ LA = 28 × 7
∴ LA = 196 m²
Let us find the cost per square meter
∵ The total cost of the sheet steel was $4392
∵ The lateral area of the container is 196 m²
- Divide the cost by the lateral area
∴ The unit cost = 4392 ÷ 196
∴ The unit cost = 22.41 dollars to the nearest cent
The sheet steel costed $22.41 per square meter
