Answer:
1) Volume of prism =
![(105)/(8)ft^3=13.125ft^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/rr1tob4s7x67da39o1n55ks708llgqk840.png)
2) Option B is the correct answer.
Step-by-step explanation:
1) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.
Base area =
![3(1)/(2) *2(1)/(2)=(3*2+1)/(2) *(2*2+1)/(2) =(7)/(2) *(5)/(2)=(35)/(4) ft^2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/h59sstp5ziki6ygs5g60o6wef3d2yscu76.png)
Volume =
![(35)/(4)*1(1)/(2) =(35)/(4)*(1*2+1)/(2)=(35)/(4)*(3)/(2)=(105)/(8)ft^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/m19wdkh4nzx2iiuzvmqkuqb62q00t40ojv.png)

2) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.
Base area =
![4(1)/(4) *3in^2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/99s45p6lo3kns02sgpuh7dz88hjo9j35g5.png)
Volume =
