Question

the side length of the base of the square pyramid in 30 cm the height of the pyramid is 45 M what is the volume of the pyramid made in cupid centimeters

Answer 1

The volume of a square pyramid is given by:

$V=\frac{1}{3}Bh$

where:

B = Area of the base

h = height

so:

$\begin{gathered} B=l^2 \\ where \\ l=length=30\operatorname{cm} \\ so\colon \\ B=30^2=900cm^2 \end{gathered}$

Therefore:

$\begin{gathered} h=45m=4500\operatorname{cm} \\ V=\frac{1}{3}(900)(4500) \\ V=1350000cm^3 \end{gathered}$
