Question

250 dam =? Cm
0,8924 km=? Cm
403,7 cm la Puterea 2=? M la puterea 2
345 cm la puterea 2=?m la puterea 2
0,00234 km la puterea 3 =? M la puterea 3
​

Answer 1

250 dam = 250 * 10^3 cm = 250 000 cm

0,8924 km = 0,8924 * 10^5 cm = 89240 cm

(403,7 cm)^2 = 162973,69 cm^2 = 162973,69 * 10^(-4) m^2 = 16,297369 m^2

(345 cm)^2 = 119025 cm^2 = 119025 * 10^(-4) m^2 = 11,9025 m^2

(0,00234 km)^3 = (2,34m) ^3 = 12,812904 m^3
