Answer:

Step-by-step explanation:

Volume of the figure = Base area * height

Base area:

Base area = area of trpezium + area of triangle

<u />

<u>Trapezium:</u>

a, b area the length of parallel sides and h is the height of trapezium.

a = 8 m ; b =  5 m & h = 3 m

\boxed{ \text{ Area of trapezium = $\dfrac{(a +b)*h}{2} $}}

                               =\dfrac{(8+5)*3}{2}\\\\\\=\dfrac{13*3}{2}\\\\\\= \dfrac{39}{2}\\\\\\= 19.5 \ m^{2}

<u>Triangle:</u>

height = 4 m & base = 8 m

\boxed{\text{Area of triangle =$\dfrac{1}{2}*base*height$}}

                           =\dfrac{1}{2}*8*4\\\\\\= 4*4\\\\= 16 \ m^{2}

Base area = 19.5 + 16

                 = 35.5 m²

Volume of the figure = Base area * height

                                     = 35.5 * 14

                                      = 497 m³
