Question

Find the volume of a pyramid with a square base that is 20m by 20m. The height is 30,000 cm.:

Answer 1

check the picture below.

now, the base is in "meters", whilst the height is in centimeters, so to get a volume, we'd need the same unit.

there are 100 cm in 1 m, therefore, in 30000 cm, there are 30000/100 meters, or 300 meters.

Explanation:

Answer 2

check the picture below.

now, the base is in "meters", whilst the height is in centimeters, so to get a volume, we'd need the same unit.

there are 100 cm in 1 m, therefore, in 30000 cm, there are 30000/100 meters, or 300 meters.


`\bf V=\cfrac{(\stackrel{B}{20\cdot 20})(\stackrel{h}{300})}{3}\implies V=\stackrel{meters}{40000}`
