You are on the job and asked to estimate the volume of a trench excavation of a simple bench. You are given the dimensions: Width: 10 yd (9.1 m3) Depth: 10 yd (9.1 m3) Length: 10 yd (9.1m3) Approximately how much material are you expecting to remove? Hint: Use these formulas to complete your quiz: Volume of a triangular prism=1/2times basetimes height times length JTE=VMMdiv P 450yd^3(344m^3) 1100yd^3(841m^3) 550yd^3(420m^3) 950yd^3(726m^3)

Answer 1

To estimate the volume of the trench excavation, we can use the formula for the volume of a triangular prism:Volume = (1/2) x base x height x lengthGiven the dimensions:Width (base) = 10 ydDepth (height) = 10 ydLength = 10 ydPlugging in the values:Volume = (1/2) x 10 yd x 10 yd x 10 ydVolume = 500 yd³Therefore, the estimated volume of the trench excavation is 500 cubic yards (yd³).To calculate the amount of material to be removed, we can use the formula:JTE = VMM ÷ PWhere:JTE = Job Task EstimateVMM = Volume of Material to be RemovedP = Production RateAssuming a production rate (P) of 1 yd³ per hour, the calculation would be:JTE = 500 yd³ ÷ 1 yd³/hourJTE = 500 hoursTherefore, the estimated amount of material to be removed is 500 cubic yards (yd³).
