Answer:
The correct answer is first option. 270 m³
Step-by-step explanation:
Formula:
Volume of prism = Base area * Height
Area of triangle = bh/2 where b - base and h - height
From the figure we can see that height of prism = 36 m
Base is a right angled triangle with base 5 m and height = 3 m
To find the Base area
Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5
To find the volume of prism
Volume = Base area * height = 7.5 * 36 = 270 m³
Therefore the correct answer is first option . 270 m³
We must know that the volume of a triangular prism is the area of the base multiplied by the height.
Let's first identify our values:
36m = height of prism
5m = base of triangle
3m = height of triangle
First, we must know the formula to calculate the area of a triangle.
Area = base × height ÷ 2
5 is the base of the triangle and 3 is the height. 5 × 3 =15
15 ÷ 2 = 7.5
The area of the base is 7.5[tex]m^{3}[/tex]
The last step we have to do to find the area of the triangular prism is we multiply the area of the triangle by the height of the prism.
7.5 × 36 = 270[tex]m^{3}[/tex]
Therefore, the volume of the triangular prism is 270[tex]m^{3}[/tex]
