Question

a solid pentaogonal pyramid has a mass of 500g. it is made of a material with a density of 6g/cm3. given that the base area of the pyramid is 30 cm2, find its height.

Answer 1

8.33 cm. *

Step-by-step explanation:

density = mass /volume => volume

= mass/density

volume of pyramid = 500/6 cm^3

1/3 * base area × h = 500/6

1/3 *30 *h = 500/6

=> h= 50/6 cm = 8.33 cm
