The base of a right prism is an equilateral triangle with side 8 cm and the height of the prism is 5cm, then the volume of the prism is - |
165 cm³ 138.56 cm³ 200.65 cm³ 180.36 cm³ |
138.56 cm³ |
volume of prism = area of base × height ⇒ volume = \(\frac{\sqrt {3}}{4}\) × 64 × 5 = 1.732 × 80 = 138.56 cm3 |
