Answer 1

@mathmath333 @AriPotta any idea?

Answer 2

9.)volume of right angled triangle prism
\(\Large\tt \begin{align} \color{black}{V=\dfrac{1}{2}bhl\\~\\
=\dfrac{1}{2}\times 4\times 5\times 10\\~\\
=100~unitcube\\~\\}\end{align}\)

similarly
10.)volume of rectangular prism
\(\Large\tt \begin{align} \color{black}{V=hlw}\end{align}\)

11.)volume of slanted cylinder
\(\Large\tt \begin{align} \color{black}{V=\pi r^2h}\end{align}\)



12.)volume of cone
\(\Large\tt \begin{align} \color{black}{V=\dfrac{\pi r^2h}{3}}\end{align}\)

Answer 3

9) 100
10) 784
11) 1329.79
12) 323.40

Do these look right @mathmath333 ?

Answer 4
