Question

The base of a right pyramid is a square of side 40 cm long. if the volume of the pyramid is 8000 then its height is : 5 cm 10 cm 15 cm 20 cm

Answer 1

The volume (V) of a right pyramid with square base of side $a=40 cm$   vertical height $H$  is given as

$V=\frac{1}{3}(a^2)H$

$8000=\frac{1}{3}(40^2)(H)$  

$H=\frac{8000\times 3}{40^2}$  

$=15cm$

➡The volume (V) of a right pyramid.
➡ square base of side a=40 cm a=40
➡ vertical height H 

=>V=1/3a^2H

=>8000=1/3×40^2×H

=>8000=1600/3×h

=>Height=15cm✔✔✔
