A well 20m deep and 7m in diameter is dug. The eart
taken out is used to make an embarkment of dimensio
22m x 14m. Find the height of the embarkment.​

Answer 1

Answer:

height of well=20m

radius =7/2=3.5m

volume of cylinder =πr^2h=π×3.5×3.5×20=770

now again ,volume of cuboid=L×B×H=22×14×h

equating both equation

770=22×14×h

h =770/22*14

h=2.5
