Question

Use two unit multipliers to convert 75 square inches to square feet.

Answer 1

In order to use two unit multipliers we will convert from square inches to cm using the following unit multiplier:

`\frac{6.4516}{1^{}}(cm^2)/(in^2)\text{.}`

and then we will convert from square cm to square feet, using the following unit multiplier:

`(0.00107639)/(1)(ft^2)/(cm^2).`

Answer:

`75in^2=75in^2(\frac{6.4516}{1^{}}(cm^2)/(in^2))((0.00107639)/(1)(ft^2)/(cm^2))=0.520833ft^2.`
