We need volume

Find volume of big cuboid then subtract the small one

For big one

  • L=25
  • B=24
  • H=8

Volume

  • LBH
  • 25(24)(8)
  • 24(200)
  • 4800ft³

For small one

  • L=25ft
  • B=20ft
  • H=8-5=3ft

Volume

  • LBH
  • 25(20)(3)
  • 500(3)
  • 1500ft³

TOTAL volume

  • 4800-1500
  • 3300ft³
