Unit Conversions Involving Units Raised to a Power

Sorry for asking three questions:

Q1.   Calculate the displacement (the total volume of the cylinders through which the pistons move) of a 5.70-L automobile engine in cubic inches.

Conversion factors:

1 mL = 〖10〗^(−3)  L
1 mL = 1 cm^3
2.54 cm = 1 in

Q2.   How many cubic centimeters are there in 2.11 yd^3?

Conversion factors:

2.54 cm = 1 in
1 in = 1 yard

Q3.   A vineyard has 145 acres of Chardonnay grapes. A particular soil supplement requires 5.50 grams for every square meter of vineyard. How many kilograms of the soil supplement are required for the entire vineyard?

Conversion factor:

1 km^2  = 247 acres
