How many cm^(3) are there in 2.5m^(3) ? How many cm3 are there in 2.5 m3? The Correct Answer and Explanation is: To convert from cubic meters (m³) to cubic centimeters (cm³), we use the following conversion factor:1 m=100 cm1\ \text{m} = 100\ \text{cm}1 m=100 cm Since the units are cubed:1 m3=(100 cm)3=1, ⁣000, ⁣000 cm31\ \text{m}^3 = (100\ \text{cm})^3 = 1,\!000,\!000\ \text{cm}^31 m3=(100 cm)3=1,000,000 cm3 Step-by-step
