Triangular prism

Calculate the volume of a triangular prism 10 cm high, the base of which is an equilateral triangle with dimensions a = 5 cm and height va = 4,3 cm

Correct answer:

V =  107.5 cm³

Step-by-step explanation:

$$\begin{gathered} h=10\text{cm} \\ a=5\text{cm} \\ v=4.3\text{cm} \\ {S}_1=a\cdot v/2=5\cdot 4.3/2=\frac{43}{4}=10.75{\text{cm}}^2 \\ V=S_1\cdot h=10.75\cdot 10=107.5{\text{cm}}^3 \end{gathered}$$
