What is the volume of a regular pyramid having a base area of 24 in.² and a height of 6 inches?
Assoli18 [71]

Answer:

48 in³

Step-by-step explanation:

The volume (V) of a pyramid is calculated as

V = \frac{1}{3} × area of base × height

here area of base = 24 and height = 6, so

V = \frac{1}{3} × 24 × 6 = 8 × 6 = 48 in³
