0.25m³= cm³
Then 150 cm & sup3; = M & sup3;
Better sum it up for me

1 m=100 cm
1m^2=100^2 cm^2=100 00cm^2
1 m^3=100^3 cm^3=100 00 00 cm^3

The bottom of a cylinder is divided into several parts, and then cut into an approximate cuboid. The cuboid is 15.7 cm long and 10 cm high?
Do not enter the process of solving formula and problem

Radius: 15.7 △ 3.14 = 5cm
Volume: 5 & # 178; π × 10 = 785 CC

3350 M = () km, 80 H = () day, 7 kg, 20 g = () kg, 3.4 H = () H () min, 15000 mm = () M = () km, 2.04 t = () t = () kg, 3.6 km2 = () ha = () m2

3350 M = (3.35) km, 80 H = (10 / 3) day, 7 kg, 20 g = (7.02) kg, 3.4 H = (3) H (24) min, 15000 mm = (15) M = (0.015) km
2.04 tons = (2) tons (40) kg 3.6 square kilometers = (360) hectares = (3600000) square meters
