A decorative mass of cheddar cheese is in the shape of a square-based pyramid with base lengths of 4.6 mm, and an apex height of 9.3 mm. How much cheddar s on display, in mm2

Solution

Volume of a Pyramid = (1/3) * Base Area * Height

Here base area = Area of the square = 4.6 * 4.6 = 21.16 mm², and h = 9.3 mm

Therefore the Volume = (1/3) * 21.16 * 9.3 = 65.596 mm³.
