  1. A continuous footing is 100 linear ft long, 24 inches wide, and 12 inches deep. About how many cubic yards of concrete does it need?

    Answer: 7.41 cubic yards

    100 x 2 x 1 = 200 cubic feet, and 200 / 27 ≈ 7.41 cubic yards.

  2. A floor measures 2,000 sq ft and the estimator applies a 10% waste factor. How much flooring should be ordered?

    Answer: 2,200 sq ft

    2,000 x 1.10 = 2,200 square feet.

  3. How many square yards of carpet are needed for a 15 ft x 18 ft room, with no waste?

    Answer: 30 square yards

    15 x 18 = 270 sq ft, and 270 / 9 = 30 square yards.

  4. A drain line slopes 1/4 inch per foot. About what percent grade is that?

    Answer: 2.08%

    0.25 in / 12 in = 0.0208, or about 2.08%.

  5. About how many standard 8x8x16 CMU blocks are needed per square foot of wall area?

    Answer: 1.125

    Each block's nominal face is 8 x 16 in = 0.889 sq ft, so 1 / 0.889 ≈ 1.125 blocks per square foot.

  6. A gable roof has two planes, each 40 ft long with a 20-ft rafter length. How many roofing squares is that, with no waste?

    Answer: 16 squares

    2 x (40 x 20) = 1,600 sq ft, which is 16 squares.

  7. For converting metric specs on a jobsite, 1 meter is roughly equal to:

    Answer: 3.28 feet

    One meter is about 3.28 feet, or 39.37 inches.
