Find the volume of a candy corn, assume they are rectangular pyramids with a length of 8.2 mm, a width of 3.5 mm and a height of 20.1 mm

Sagot :

Given:

Lenght =8.2mm , width = 3.5mm and height = 20.1

The volume of pyramid is given by,

V=1/3 (base area) (height)

As it is rectangular pyramid,

first find area of reactangle . this will be base area for pyramid.

area of reactangle=lenght * weight

[tex]\begin{gathered} A=l\cdot w \\ =8.2\cdot3.5 \\ =28.7\text{ cm}^2 \end{gathered}[/tex]

Volume is,

[tex]\begin{gathered} V=\frac{1}{3}\cdot A\cdot h \\ =\frac{1}{3}\cdot28.7\cdot20.1 \\ =192.29\text{ cm}^3 \end{gathered}[/tex]
