Perpendicular prism

Calculate the volume of the perpendicular prism if its height is 60.8 cm and the base is a rectangular triangle with 40.4 cm and 43 cm legs.

Correct answer:

V =  52810.88 cm³

Step-by-step explanation:

$$\begin{gathered} h=60.8\text{ cm } \\ a=40.4\text{ cm } \\ b=43\text{ cm } \\ {S}_1=a\cdot b\mathrm{/}2=40.4\cdot 43\mathrm{/}2={\displaystyle \frac{4343}{5}}=868.6{\text{cm}}^2 \\ V=S_1\cdot h=868.6\cdot 60.8=52810.88{\text{cm}}^3 \end{gathered}$$
