A bat manufacturing company made a huge bat for charity and got it signed by world cup winning team. The dimensions of the bat which is in the form…

Radius of cylindrical part \(\displaystyle =\frac{0.1}{2} \mathrm{~m}\) or \(\displaystyle \frac{1}{20} \mathrm{~m}\) Volume of wood = Volume of cuboid + volume of cylinder \[\begin{aligned} & =2 \times 0.5 \times 0.1+\frac{22}{7} \times \frac{0.1}{2} \times \frac{0.1}{2} \times 0.7 \\ & =\frac{211}{2000} \text { or } 0.1055 \mathrm{~m}^{3} \end{aligned} \] Total surface area of bat = TSA of cuboid + CSA of cylinder \[\begin{aligned} & =2(2 \times 0.5+0.5 \times 0.1+0.1 \times 2)+2 \times \frac{22}{7} \times \frac{0.1}{2} \times 0.7 \\ & =\frac{5}{2}+\frac{11}{50}=\frac{68}{25} \text { or } 2.72 \mathrm{~m}^{2} \end{aligned} \]
