A landscaper dug holes. It takes him 1 hour to dig a hole 2 feet deep, 2 feet long and 2 feet wide. Assuming everything remains the same, how many hours would it take him to dig a hole 4 feet deep, 4 feet long and 4 feet wide?

  • math..word problem -

    the volume of the first hole is 2x2x2 or 8 cubic feet
    so his rate is 9 cubic feet/hour

    the second hole is 4x4x4 or 64 cubic feet.

    so if he can dig 8 cubic feet in 1 hour, how many hours do you think it would take him to dig 64 cubic feet?

    I am confused.
    You said in your first statement that his rate is 9 cubic feet/hour. But you also state that he can dig 8 cubic feet in 1 hour.

    I am assuming that if he can dig 8 cubic feet in 1 hour that it would take him 8 hours to dig 64 cubic feet. (64 cu. ft divided by 8 cu. ft.) Correct?

    clearly a typo,

    yes, you are right, it would take 8 hours.

  • thank you -

    Thank you Dr. Reiny.
