The base of a right prism is an equilateral triangle with each side measuring 8 cm. Given that the height of the prism is 10 cm, what is its volume?
Show answer & explanation
Correct answer: D
Explanation
Side of the equilateral triangle = 8 cm, Height of the prism = 10 cm
Volume of the prism = Area of the base × Height
Area of the equilateral triangle = (√3/4)a²
Area of the base = (√3/4) × 8²
= (√3/4) × 64
= 16√3
Volume = 16√3 × 10 = 160√3
