Answer: 8 cm
Step-by-step explanation:
If the height of the pyramid is h,
The volume of the pyramid is, 1/3*base area*height=1/3*48*h
(The base area of the pyramid is as same as the base area of the cuboid)
The volume of the cuboid is, base area*height=48(20-h)
Considering the total volume,
1/3*48*h+48*(20-h)=704
By solving the above equation for h, the height of the pyramid can Be obtained
