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)

To estimate the volume of the trench excavation, we can use the formula for the volume of a triangular prism:<br /><br />Volume = (1/2) x base x height x length<br /><br />Given the dimensions:<br />Width (base) = 10 yd<br />Depth (height) = 10 yd<br />Length = 10 yd<br /><br />Plugging in the values:<br />Volume = (1/2) x 10 yd x 10 yd x 10 yd<br />Volume = 500 yd³<br /><br />Therefore, the estimated volume of the trench excavation is 500 cubic yards (yd³).<br /><br />To calculate the amount of material to be removed, we can use the formula:<br />JTE = VMM ÷ P<br /><br />Where:<br />JTE = Job Task Estimate<br />VMM = Volume of Material to be Removed<br />P = Production Rate<br /><br />Assuming a production rate (P) of 1 yd³ per hour, the calculation would be:<br />JTE = 500 yd³ ÷ 1 yd³/hour<br />JTE = 500 hours<br /><br />Therefore, the estimated amount of material to be removed is 500 cubic yards (yd³).
