The raft

The raft for washing beets has the shape of a prism with the base of an isosceles triangle, the base of which is 6.8 m (width of the raft) and a height of 4.8 m (depth of the raft, height of the triangle). The raft is 35 m long (prism height). Calculate the float volume!

Correct answer:

V =  571.2 m³

Step-by-step explanation:

$$\begin{gathered} a=6.8\text{m} \\ h=4.8\text{m} \\ l=35\text{m} \\ S=\frac{a\cdot h}{2}=\frac{6.8\cdot 4.8}{2}=\frac{408}{25}=16.32{\text{m}}^2 \\ V=S\cdot l=16.32\cdot 35=571.2{\text{m}}^3 \end{gathered}$$
