Question

A flower vase has a volume of 320 cubic centimeters (cm3). Use the fact that 1 inch is equal to 2.54 cm to convert this volume to cubic inches (in”).

Answer 1

Since 1 inch = 2.54 cm

Then 1(inch)^3 = (2.54)^3 = 2.54 * 2.54 * 2.54 cm^3

1 (inch)^3 = 16.387064 (cm)^3

Since the volume = 320 cubic cm

To convert it to cubic inch divide it by 16.387064

The volume = 320/(16.387064)

The volume = 19.52759811 cubic inches

1 in^3 : 16.387064 cm^3

? in^3 : 320 cm^3

By using cross multiplication

? = (320 * 1)/16.387064

? = 19.52759811 inch^3
