Question

Martin's suitcase has a volume of 1,080 centimeters cubed. Lily's suitcase measures 9 inches wide, 13 inches long, and 21 inches high. What is the combined volume of the two suitcases?

Answer 1

Explanation:

1 inches = 2.54 cm

9 inches = 22.86 cm

13 inches = 33.02 cm

21 inches = 53.34 cm

volume of the first suitcase = 1080 cm³

volume of the second suitcase = 22.86 cm × 33.02 cm × 53.34 cm = 40263.02 cm³

total volume = 41343.02 cm³

Answer 2

`V = 41343.016\,cm^(3)`

Explanation:

The combined volume of the two suitcases is:

`V = 1080\,cm^(3) + (9\,in)\cdot (13\,in)\cdot (21\,in)\cdot \left((2.54\,cm)/(1\,in) \right)^(3)`

`V = 41343.016\,cm^(3)`
