The volume of a rectangular slab of concrete needs to exceed 72 cu. ft. If the length is 12 feet and the width is 8 feet, how thick does the concrete slab need to be?

  • algebra -

    12*8*thickness>72

  • algebra -

    would I replace the word "thickness" with 96? 12*8*96 > 72?

  • algebra -

    (12 * 8)t = 72
    96t = 72
    t = 72/96
    t = 0.75 inches
