frosja888 [35]

<u>Answer-</u>

\boxed{\boxed{\text{Mass}=10.0447256\ ton}}

<u>Solution-</u>

The dimensions of the cuboid is, 80×80×140 cm

So, its volume will be =80\times80\times140=896000cm³

The dimensions of the cylinder is, radius = 40cm, height = 70cm

So, its volume will be \pi r^2h=\pi\times40^2\times70=351792cm³

Total volume,

V=V_{\text{Cylinder}}+V_{\text{Cuboid}}\\\\=351792+896000\\\\=1247792\ cm^3

As we know,

\Rightarrow \text{Density}=\dfrac{\text{Mass}}{\text{Volume}}

\Rightarrow \text{Mass}=\text{Density}\times \text{Volume}

\Rightarrow \text{Mass}=8.05\times 1247792=10044725.6\ g

\Rightarrow \text{Mass}=10044725.6\times 10^{-6}=10.0447256\ ton
